PPE ported fuel fitting vs stock Pics.

FRPV on a LB7 is not on the rail,Its on a juction block before it enters the rails
lb7s also go to both rails induvidually,unlike the newer trucks

FRPV is of no resrtiction as Mike said....Its just a high pressure relief valve

 

[sweetdiesel]

I see thanks, I guess maybe I should install another pressure sensor and see if I have an unbalance between the rails.

Things that make you go HMM Now how the heck do you install a sensor on each rail:baby:

HMM,Great now im going to be up all night:rofl:

I am thinking on the front side of " our " drivers side and the rear of " our " passenger side. " our " for us and " them " for Lennart and Mick. :joker:

As far as reading them simultaneously ????? One at a time I guess for now.

dredging up the past :thumb: I got a spare driver's side fitting off a buddy that did his with the PPE, and I drilled it to .90 and installed it.

My question is -- can I drill out my old one to .60 and replace the stock passenger side with it? Or is the fitting on the pass side totally different?

Thanks in advance!

So is any of this needed for an lb7
it Went both ways so I'm sort of lost?

I don't think you will see any gain, but it also won't hurt


Fwiw you don't drill the fitting on lb7s but the office that sits behind the fitting

 

[duramaxrize]

What kind of gain can you expect on a stock set up? Is this a must if you have a lift pump installed on a lly?

i wouldn't waste your time... but that is based off of my own experience

Either way you can buy a drill bit for a lot cheaper than the so called "ported" fittings.

That depends, mine were a one piece fitting. I think the earlier model year LB7's were like simon is describing, while the later ones were one piece like mine.

Anyone willing to post a pic? Or a "how to" would be nice!Thanks

I didn't get my cp3 fitting in yet, but I did the driver's side so far. I can tell the difference in what I'll call the "attack time" it takes for the AFRP to match the DFRP. With the driver's side drilled the two mirror better then before.

Still hoping someone can answer my question though :thumb:

Could be Mike. Never seen one but it's not the first time I heard that


Thanks for posting that to avoid confusion for some guys:hug:

Sweetdiesel. I'm not able to find it man. I went back to 2006. Could it be labeled deferent?
Sorry to derail a little
