AFPR (thinking outside the box)

[MadPSI]

Well, Nick (nick041881) and I were plumbing the fuel system and we ran into a problem with the fitting to the AFPR hitting the intake. After a few minutes of wondering what to do I decided to try this. Will it work, or does the AFPR have to be upright for some reason? He's using F.A.S.T., so doesn't he just have to adjust a base fuel pressure then let the computer take care of it?

is the fuel rail pushed all the way down on the injectors? doesnt look like it...maybe you could find a tighter 90 degree elbow to run it upright?

Can you still get a vacuum line on it?

The only think I can see is it may affect your return.. I am not sure how much pressure there is in the return versus the pressure side... but you should be able to start it and see... if it is not returning correctly.. you will nkow it.. the FP will start rising and the truck will probably get rich and stall. If it is OK at idle should be ok across the board... someone else may have another reason.

It does look goofy though... :lol:

my solution to the same problem is to rotate the AFPR 90 deg
(bottom fitting facing back) by relocating the mounts on the rail

My welder guy feels this is not a big deal but likes my other
idea of altering the orig design if the rails and/or the AFPR
were aftermarket or cust fabricated

a third approach would be to fabricate an adapter with
1 set of holes to mount adapter to rail
another set to mount the AFPR to the adapter with the hole
for the sealed fitting larger than the o-ringed nipple so it
would still seal in the rail, not the adapter, but just not go in as deep

i am to the point now that i just want to get this truck running so brandon and i can have fun. if it works this way then i think it might stay this way...at least until startup. i would eventually like to get an aftermarket rail that eliminates the problem. maybe in a couple of months.....

I love to do hard lines....
to night i took another look at my same dilema, i took my handy bender

and modded it !

i cut the flat material away from the finger to the 0 deg mark, which
allows the fitting to sit between the rounded portion and the finger butted
up against 0 deg.

then i threaded a tube on to the fitting to make it long enough to sit
properly under the finger which allows me to make the tight bend
to fit under the AFPR

i think you will find that the height of the 90 degree end that is on that hose is taller than a regular non swivel 90 degree An6 fitting . A 90 swivel fitting that is not a hose end style might even be shorter.
but regardless i do know that i didnt do it with a 90 dgeree hose end but insteadI used angled fittings to a straight hose end.

By changing to a different fitting i think you will then get the clearance you need.

I used An lines for my fuel lines and have the same afpr from pte.

It is a tight just fit but it does fit without making things look ass backwards.

As i recall i had to put the elbow on the afpr and then lower that and the rail assy into position and just keep adjusting the angle till you get it correct.

But you would have to be suicidal to want to have to adjust your fp using the setup like you have it upside down.

Just take a little time and you can get the proper angle to bring the fuel line in with the proper fitting selection.

earls makes a tubing adaptor so that you can use the elbow from the stock line and then go to a-6 fitting. it's a compression fitting. thats what I'm doing. use the first few inches of stock so that it all fits right and you can stil work on it, then adapt to an stuff.
