Im pretty sure mine is failing, I am running too rich. Question is how easy is this to replace? And honestly I do not know of its exact location or what it looks like. Trust I am a quick learner.
Any help?
Also should I go ahead and buy from St. Charles or another distributor?
Thanks.

Consider it read. But how easy was the install? On a 1-10 scale.

What make you think you are running too rich, and why do you think its the fuel pressure regulator?

Pretty easy if you have tool to remove internal ring grommet (??? see pic belowOriginally Posted by JHarris1385
) something like that:
Just in case you want go with aftermarket, do not buy Standart Motor/GP Sorensen unit, Neihoff/Borg Warner should be fine. They are available in Checkers at least.
2001 Isuzu VehiCROSS (build in progress): 4JX1/A340/part time, 2" body lift, front Aisin hubs, rear Aussie Locker, 4.56 gears, OEM rear sway bar disconnect, AirFlow snorkel, cabin air filter
1980 Jeep Cherokee (assembling): 1.5" body lift, TBI, HEI
1987 AMC Eagle: stock

Thanks alot. My previous post(s) conclusions led to the FPR. I have a tool similar, for use on the John Deere. Thanks. SHould I order from St. Charles?

This is the FPR showing correct assembly, and part #. its at the drivers side rear of the injector fuel rail.

Just compare price from Checkers and Isuzu and select cheapiest source. I think it is exactly same part in different packages (Neihoff/Borg Warner/Isuzu).

Has anyone ever tried an adjustable fuel pressure regulator?

So I finally got my FPR in mail today from drivewerks.com. But I come home to find out that my retaining ring pilers tips are too large to fit through the holes.
Question is are these pilers easily purchased at HD or Lowes in smaller tip sizes?

In worst case you can use file on what you have

Bought some new ones with multiple tips and angles. They are great. BUTTTTTT. Iv got the fuel rail almost completely off and can not get the bolts that attach the black cover over the fuel pressure regulator unbolted from the common chamber. Even PB blaster has not worked yet.
Ill post pics later, if you all do not know what bolts I am talking about. They are completely round and require a large allen wrench. Talk about leverage with an allen wrench.
Has anyone done this repair yet?
Super VXer
If I understand correctly, you talking about the bolts marked as 340 here:
Mine bracket was holded with the internal hex on the side and regular metric bolt on the rear actuallyThe side bolt was replaced with the regular bolt at the end, though - I also almost rounded it with not 100% fitted tools
Super VXer
Nice diagram, where did you pull that from?
I gave up on it for now going to try tomorrow maybe the pb blaster will soak in more by that time.
I almost busted the allen wrench trying to lossen it.
