Is this the normal or high pressure version? Thanks for posting the deal BTW.

 

I forgot to mention. We have both high and low pressure. When purchasing them, please include whether or not you want the high or low presure.

 

what pressure do we need exactly? I am thinking to go to turbo or SC, but not until an insane deal on those comes along or at most next spring. Should I just wait until I get one of those? or is this something I can use on my car now as it is?
thanks

 

If you going with turbo or SC, you will need the high pressure. SC/Turbo get more fuel via raising the fuel pressure. High pressure fuel pump will be able to sustain the flow rate "GPH" even at higher fuel pressure. One draw back is you will need a fuel pressure regulator since the OEM can't regulate the HP fuel pumps.

 

1) So what is this unit for above price?? High pressure or lower pressure unit?
2) What is the price for the higher pressure version?
3) Are they in stock? What is the delivery time.

Thanks.

Tony, so you recommend the higher pressure version or is the normal 255lph one good enough. I know they are similar except the HP version doesn't lose it's fuel flow as fast as the pressure goes up.

 

You will need the high flow version, Jeffy.

 

Does this help your performance if you don't have any types of mods?
Thanks,
Paul

 

What if I'm running NOS? High or low pressure? Am I correct in assuming that I need high pressure as well?

 

Thanks Kevina!

 

Oh another question ... (F U Kevin!)

How much extra to ship to Toronto, Canada? There may be several guys up here that are interested so maybe u can ship a whole slew @ once ... I'll post in the Canada forum to see what the interest is.

 

Canadians don't deserve high pressure fuel pumps.

4th gen installation (easier) is way different than 5th gen installation.



You're welcome, Jeffy.

 

interested!! whats the regular price?

 

Hey guys. Woo, there are a lot of replies. Well it doesn't matter if its low pressure or high pressure. It will still cost only $105 and that includes shipping. And yep, if you guys upgrade on a turbo kit, you will definially need a bigger fuel pump. I suggest the high flow one.

If you guys are interested, email me at sales@dsmtrend.com. Include your Name, shipping address, and year model. We have them ALL IN STOCK and ready to be shipped. Once we receive the payment, we will ship immediately. I suggest you guys using Paypal since its faster, but if not, we accept CC over the phone/email, or money order/check.

 

This is a good hookup. I got the ball rolling on this yesterday
when I found this on a DSM forum I visit due to all the work I do
with a friend on his supersweet GSX.

Pricing:
Both the low-pressure and high-pressure versions are available
FOR THE SAME PRICE.

Here's an excerpt from the FAQ on Walbro Fuel Pumps at
AutoPerformanceEngineering.com
(And NO, this deal is not from AutoPerformanceEngineering.com)

Q: How will I know when I need a new pump?

A: If your fuel pressure at wide-open throttle (WOT) falls off, that is a good indication that your current fuel pump can not provide the required amount of fuel. Either the voltage to your pump is weak, or your pump isn't manly enough.

If you plan on driving your vehicle in its stock configuration for the rest of its days, a new pump should not be required unless your stock pump fails. If your stock pump fails, why not put one of these in there? It's probably cheaper than a replacement pump from the dealer.

Q: Which pump is right for me?

A: If you're just going to replace your pump with something that is near stock because your stock one croaked, or if you are not going to do any mods, the 190 ltr/hr pump may be all you need.

Notice that the only difference between the 'normal' 255 ltr/hr pump and the 'high pressure' 255 ltr/hr pump is the flow above 50 psi of fuel pressure. Unless you are running a high base fuel pressure, or are running some serious boost levels, the normal 255 pump should be enough.

I'm not trying to sell you a giant pump just to get a couple more bucks out of you. But, in my experience, when folks start modifying their vehicles, they never seem to make it fast enough. I'd hate to sell you a pump this month, then have you contact me in six months, telling me that you need more fuel, because you got a bigger turbo or some other go-fast part that is going to need more fuel. The cost difference is small; just consider it a cheap insurance policy. If you get the high-pressure pump, you'll probably only have to get into the fuel tank only once, too.

Your best source for accurate info is probably your vehicle-specific mailing list.

Q: How much horsepower will your pumps support?

A: Let's use the formula that says horsepower (HP) =lb/hr (fuel) / BSFC. If we assume BSFC of .5, then HP = 2 * lb/hr. Then, if we round the weight of a pound of fuel to 6 pounds HP = 12 * gal/hr. So, if we assume .5 BSFC, then you can actually multiply the numbers in the flow charts by 12 to compute supported horsepower.

For example, If you look up the flow rate of the 190 ltr/hr pump in the Overview section, you will see that it will push 36 gal/hr at 50 psi with a 12 VDC power source. If your engine is pumping out 500 hp when the fuel pressure is 50 psi [@ 12VDC], you probably won't want to use the 190 ltr/hr pump [36 * 12 = 432].

Remember, that forced-induction engines typically raise the fuel pressure under boost. Be sure to take into account that you will have a higher-than-base fuel pressure under boost.

Q: Do I need an adjustable fuel pressure regulator, too?

A: Need... no, but you may *want* one. If you are modifying your vehicle for extra performance, chances are you will need more fuel for those heads/boost/etc. An adjustable fuel pressure regulator is a way to fine-tune the fuel system for maximum performance after you've added that new pump.

Q: Will a high performance pump do anything *bad* to my vehicle?

A: If you are talking about fuel economy, no. The fuel pressure regulator will just return all that extra fuel to the tank... keeping those lines cool.

If you're talking about the fuel lines/filter/etc., I don't think so. The only time you see higher-than-normal fuel pressures is if you get an adjustable fuel pressure regulator and really crank it up.

If you're talking noise.. maybe. I've heard from some folks that claim the Walbro pump is just as quite and others that say the pump does make more noise. I don't know why some are louder than others... maybe installation techniques.
************************************************** ******************

 

Wow thanks for the reply. I might be calling you guys!

 

I know for my application the 190lph version will support up to 400hp. Take a look a the chart on here and do some calculation.
http://www.autoperformanceengineerin.../fuelpump.html

Bascially...the formula is "HP = 12 * gal/hr" My 190lph fuel pump flows 46gph @ 50 psi. 432 = 12 * 46. I will not be running anything higher than the stock WOT FP of 43 psi since I'm running a wet kit.

 

Is there any danger of running the 255lph on a stock car then?

 

Any SC/turbo max..should get the 255lph HP (high pressure). I just took a second look at the specs of both. The regular 255lph won't do it at all. Looks like regular 255lph is only good for people running a 300 shot wet kit.

 

Your fuel pressure will be alittle high if you are still using the OEM fuel pressure regulator.

 

Hey guys nice price!
Do yall do C.O.D.?
If not then i can go paypal

 

For nitrous applications, you definitely want the high pressure one.

BTW, this is a good deal!

 

Hey, we've already received a few orders from maxima.org. Well sorry we do not do COD. But we do accept paypal. As listed before on my other thread, you can send your payment to sales@dsmtrend.com

Please include your Year model, Name, and shipping address. We will ship as soon as we receive your payment. Remember its $105 and that includes shipping.

 

is this an inline fuel pump that goes on the frame rail or does it just replace the stock one? i am doing 75 shot of nos and stage 2 turbo.

 

This is the intake one. It will replace your stock fuel pump. IF you want an external pump, it will cost you $139 shipped. The external is also a 255lph but it is rated to put out up to 650HP.

 

Is the fuel pump that we can just replace the stock one or I have to add on after stock fuel pump?

 

Hey ... you may have missed my other post .. how much to ship to Toronto, Canada? The guy that posted b4 is also from Toronto!

Hey Daniel!

 

How difficult is it to install this fuel pump as a replacement? And how about the fuel pressure regulator?

I'd be interested if I could do the work myself or if installation is cheap at a shop.

 

You going sc, turbo or nos? If not, there shouldn't be a reason to have to replace your newer fuel pump already. If you plan on serious power, I think it's just a pull the back seat and access the fuel tank from above thing. I know the 3-gen/4-gens are fairly easy. Don't know about the 5-gens. Hit up Y2Kevse and ask his ghey butt how he did his

 

If you want to ship to Canada, it will cost an extra $5. As for the replacement, all you need to do is take out your stock fuel pump and replace it with the new walbro. It is not hard. Just a few bolts, then plug and play.

 

I'm already SC'd

I saw the instructions for the 4th gen. I'm still uncertain how close most 4th gen instructions apply to the 5th gen. The 4th gen instructions make it look easy.

 

The 5th gen install is different. You'll have to shave a part off the pump to get it to remotely fit. I knew I should've taken pictures when I did the install.

 

It's never too late to take it out and snap some pics

 

To everyone that got in on this deal:

Ok it has been a week and half, that I paid, and yet to have the fuel pump shipped, I get an auto response e-mail after i e-mail them saying someone will contact me within 24 hours, but never get an e-mail, has anyone else had any problems............Bernie

 

Yeah, I ordered one, got emailed back within a day or two, and they shipped the pump shortly after I paid. I just got it yesterday.

No problems at all.

 

will these be available in a few weeks?
i'm waiting on a supercharger to come in.
Thanks

 

How do you plan to install it? According to Y2KevSE, it's not a direct fit for the 5th gen. If you make some modifications to it, please take some pictures so we can see how it's done.

Thanks,

 

They always are. If this special ends they only cost $118 elsewhere, so its not like you're saving that much money.

 

Hey Guys. The deals for the fuel pump is still going on and it'll be on for a while longer. So if anyone still wants the products, just email me at sales@dsmtrend.com.

 

ok well first get back to me, to let me know the status, I have even called 2x no call back or e-mail
