Pics of your adjustable fuel pressure regulators...
Please post some pics of your adjustable fuel pressure regulators installed on 2002 and 2003 Maximas.
There is very little info about how to actually install these in the 2002-2003 Maximas.
For those wondering, I plan on bumping up the pressure from 3.5 BAR (Stock) to 4.0 BAR, then pulling fuel via my VAFC-II. This is the "ghetto" way to advance the timing a little.
Thanks.

I'm currently looking for some injectors also. How much should a set of 6 go for?
And say I upgrade my fuel pump to the Walbro 255, can I run like 70PSI of fuel pressure as long as I compensate for it with the VAFC, or is there a maximum that the hoses can handle?

After more research, I am doubtful that this can even be done on the return-less style fuel system found on the 3.5's.
According to some 350z forums, the fuel pressure regulator is located in the fuel pump, inside the gas tank.

While you're on my350z, check the classifieds for some injectors, that's where I got mine from a few years back for 90$ shipped. A lot of guys on there are always selling since they're like to boost, etc.

SR20DEN has done it, he explained to me once, and it's on here somewhere, but I forget. Search for threads here started by him, he also did 70PSI.

What I don't understand, is how he incorporated a FPR into that setup.
I don't get how he did that without a return line...
All of the threads are from like 2002, and most of the pictures are no longer available.
What would happen if I got one of those in line Walbro pumps and just put it in series with my fuel line? Would something just pop because there is no way for the fuel to recirculate? Can these pumps be ran "dead head" and if so, what pressure will I end up with?
It's 4:36 AM and I am not going to bed until I figure out a way to raise the fuel pressure on the returnless systems found in the 2002+ Maximas!!!!
