I am trying to buy a new FPR for my car. However, the FPR I want which is made by Aeromotive uses 3/8NPT fittings. The other Aeromotive FPR that is commonly used by some of ya'll uses -6AN fittings, which is equivalent to 3/8.

My problem is that my car has 5/16 fuel lines. I am having a hard time finding 5/16 barb to 3/8 NPT. I can find them on McMaster-Carr, but they are sold in a 10 pack. I also considered stuffing the 5/16 hose onto the more common 3/8 fittings, but I am worried I won't be able to remove the hose from the larger fittings.

What kind of setups are ya'll using? I am trying to avoid using a bunch of expensive fittings, but like I said I can't find much online in the 5/16 size.

Help!

 

These sites have them:

• http://www.newageindustries.com/data...BarbedFittings
• http://olsen.thomasnet.com/item/pipe...38516?&seo=110

Plus a bunch more results from Google, checked with all of them to see if they sell individually? Of course, I have no idea how 'fuel safe' nylon fittings are.

 

I am using 3/8 lines. My fuel line was cut way to close to the rail when I got it from the junkyard. So I cut off the crimped connector and slipped on the 3/8. I did use two clamps per fitting to secure them.

 

You may have better luck looking for 5/16 barb to 1/4 NPT in brass. Then get a 3/8x1/4 brass bushing to screw into the fpr. I got mine at Home Depot in the plumbing dept.

 

Thanks for the suggestions guys.

I totally forgot that most of the parts I will need are available at Home Depot, Lowes, ACE or McClendons. I guess I don't need to sweat the online stuff.
