Fuel Pressure Regulator

[JHarris1385]

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 below ) 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.

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?

I picked up a set of these at Advanced Auto before I started my S/C install. $14 and comes with a couple interchangable head sizes. Works great for snap rings like the one used on the fuel regulator.

That's where I bought mine too that I used to replace my fuel pressure regulator...also used them on the snap-ring inside the front hubs during wheel bearing repack!

FINALLY REPLACED MY FPR.....

That 340 bolt on the back of the chamber is a pain in the *****. I wonder how anyone else got that loose. ??? Jolly?

Anyways. I average 13.6 mpg prior to this change and hard start ups (cranking the key while depressing the gas pedal for about 7 seconds each time), misfire codes daily and lots of gas smelling exhaust. But remember I am lifted and running 20'' chrome rims or 265-75 tires otherwise.

After replacing it. I was crusing at 60ish mph and saw on my scan gauge for the first time instant mpg over - 20 -. Also, it has fired up each time like it should with no gas pedal depression or exhaust. And I drove all day without a misfire code.

-- I would advise everyone to at least look at and clean your FPR even if you dont have the symptoms I do. Mine was very dirty and full of debris.

John,
hey, good to hear you got it replaced! you mentioned cleaning?? do you think its a cleanable part? and what did a new fpr cost you??
just curious.....all these post about better mileage lately is encouraging....i know it will never be great mileage in a vx, but better is always good!!
thanks
