what kind of fpr do I need?

[pj91gsx]

I need a fpr for my setup. What kind should I use? I have a walbro 255 hp.

 

[VTEC_THIS]

Most people go with the aeromotive fpr's. Pick one up on the classifieds, you'll find it for a lot cheaper then buying new.

You need an adjustable FPR that allows adjustments up and down (some only allow increasing fuel pressure). You also need one that rises on a 1:1 ratio as boost increases.

I would suggest looking at Aeromotive AFPR's as they are proven time and time again. Here's a few kits that include most, if not everything, needed to install an AFPR. Just make sure that you have all the fittings, adapters, lines, etc. that you need. Also, these kits can be had with different hose/fitting configurations (SS braided line or rubber fuel line, AN fittings or Push Lock fittings, etc.).

I am also looking for a fpr for my friend, he just needs to turn his fuel pressure down. he has a 92 tsi.

I have heard nothing but good things about Fuelab FPR's.
STMDSM - FUELAB Fuel Pressure Regulator

could my friend just throw a cheap fpr on his car. he has very few mods. he has the 255 hp. and needs to put the stock pump in or get a fpr.

fuel mods is something i would not go cheap on. A cheap fpr which has not been proven is a recipe for disaster. I wouldnt want to risk my engine just to save 50-100 bucks.

 

[pj91gsx]

yea. i should get my friend to take out his walbro 255.

Don't forget the feed line to the fuel rail, if you haven't already dealt with that.

is that really neccessary. Im just going to run a 16g and tune it.

 

[snowborder714]

It's not really necessary but that line is a big restriction in our fuel system.

 

[pj91gsx]

ok. I just want to spend my money where it matter most.

 

[DSMunknown]

is that really neccessary.

Yes, it is.

 

[snowborder714]

Yes, it is.

Can you explain how it's really necessary? I've never read or been told that - just that it's something you really should do. But it wouldn't really hurt to not do it.

 

[No_Skillz]

Your stock feed line will support your 16g with no problems. I run a PTE5031 at 20psi and have never even thought about replacing that line.

 

[DSMunknown]

Is rewiring the fuel pump really necessary? From a performance standpoint, yes. Can you get away with not doing the rewire? Sure, but I would never ever recommend it. Same goes here.

Difference in opinions, I suppose.

 

[No_Skillz]

With a non-rewired fuel pump, engine performance is actually directly affected, which is something I used to see with DSMLink - running lean and knocking when electrical power was heavily in use by AC, headlights, stereo. However this thread is the first time that I've ever heard that the stock fuel feed line should be replaced.

 

[1992awdlaser]

I run 28psi with my 50 trim on pump and race gas with the stock feed line. I don't have any issues. Replacing the feed line will lower idc but it is by no means needed.

 

[pj91gsx]

Is there a way to tell if a fuel pressure regulator adjust 1:1 with boost?

 

[snowborder714]

It should say on the product's page:

Fuel Pressure will rise on a 1:1 ratio when referencing boost.

Or do the research on here. Or call the company directly.
