Fuel Pressure Regulator

[uncle_asa]

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?

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 actually The side bolt was replaced with the regular bolt at the end, though - I also almost rounded it with not 100% fitted tools

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.

For the diagram, check the right sidebar under "downloads".

Go to Sears & get a set of 3/8" drive metric allen wrenches (that fit on a ratchet) if you haven't already...they work tons better than the cheapo L shaped ones.

It is from Isuzu EPC which is normally used in the shops to identify part. You can get a copy of it from (4 files):

Other very usefull documents:
Workshop manual (the best source to know how to unscrew something, I prefer it to the s/w from Tone): http://rapidshare.com/files/17008740/IV00.01.pdf
Electrical Troubleshooting Manual (the one that was distributed by nfpgasmask in paper form, scanned): http://rapidshare.com/files/17003942/ETM_VX99.pdf

Hey Uncle, I sent the workshop and electrical manual you sent me to Moncha for uploading here. It's under downloads/manuals. What are the other documents you have listed here?

I'm not sure about US, but in Russia we have ability to request parts by factory part number, so Isuzu Electronic Parts Catalog (EPC) is very usefull here. And also it gives you a tip on whether some parts could be bought splitted or only assembled (gaskets, motors, etc).
Probably there no more other manuals related to VX directly, but there Workshop Manuals for Troopers and Rodeo/Amigo. So, if someone wish to install manual hubs, for example, he might get a tip on how that done on Trooper

Update: Could not for anything get those bolts off.

SO instead I decided to paint the honey comb on my grill white. And my cladding screws silver. Pics comin soon.

Any suggestions of what to do with those bolts? Or how else to get that FPR out?
