Aeroquip SS Fuel Line Kit

[DUNE RACER]

Vaughn, the fitting on my SPA sendor is a male 1/8 NPT. Anything would be better than the schrader valve for me.

 

[Brandon]

I think I got it solved, it is not with the tee's, press test ports will be with 6n male to 6n female with a test port in between, we found them, the exact product was not listed in the jegs or summit, but it is a 6n union with a test port. .

exact part number to come soon

Vaughn and Dune Racer,
I just purchased a fuel pressure gauge and since I have the Aeroquip lines, I have the same problem that you do. I ordered some fittings from Jeg's when I ordered my gauge. One of those is from Russell. It is -06 on each side with a 1/8"npt in the middle. Made for fuel pressure gauges. I can cut the line between the filter housing and the injector pump and slip the adapter in there. I think that is what you guys are looking for. E-mail me for part number.

Jeff. . please post it so we can look at this later and refer others to this link...

Brandon, is that a Parker union then? Good job on tracking that down! Please let us know if it works out good. I would like to order a few to try out for myself.

* However *

I am not ready to give up on my -6AN banjo fitting with stock schrader valve drilled out idea though. With the Aeroquip -6 banjo fitting in place at the injection pump, you only need one adapter to connect your pressure gauge (-4AN male to 1/8" male pipe) . That nets a total of 3 threaded connections at the injection pump (banjo bolt, adapter, and gauge line/sensor) with only ONE inline with the route of fuel supply going to the injection pump. Even better, a pressure gauge like AutoMeter's with a -4 hose, which would hook up with no adapter, netting 2 threaded connections total at the injection pump.

With a union fitting and standard -6 Aeroquip line, you have a total of 4 threaded connections (weber bowl fitting, -6AN union, gauge line, fuel hose) with THREE connections inline with the fuel supply to the injection pump. I am not saying this to fault the -6AN union setup, but common sense says less fittings = less potential for leaks.

One last note on the -6AN banjo fittings. . . the inside cavity where the fuel enters the fitting around the banjo bolt is much more open and less restrictive compared to the stock -4AN banjos. Now, with the stock banjo/schrader valve bolt drilled out with an 13/64" drill bit, which still leaves plenty of material for strength, the combined diameter of the holes nets a cross-sectional area of . 130" square inches, which is larger than the 3/8" -6AN cross-sectional diameter of . 110" . Of course the banjo fitting is not a smooth "straight-pipe" flow design like the nice curving Aeroquip fittings resulting in a little more resistance to flow, but I think this will cancel out with the larger equivalent size of the drilled holes in the bolt.

Of course the -6AN banjo bolt idea is all for naught if it doesn't bolt up nicely to the injection pump. I am still waiting for these items, on back order, to arrive, and then we shall see!

The part number is 799-7000. Go to Jeg's website at www.jegs.com (I can't do links), enter the part number on part number search. The page that contains Russell fittings comes up. Scroll down until you find that part number. It has a thing there that says "view item". Click on it and it will give you a picture.

The adapter will also require the -06 hose ends to screw into it and some fittings aand line to run to the isolator. I have all of this on order so I will see next week if it all works out.

 

[DUNE RACER]

This is the same adapter I've been asking about. Its also available at Summit Racing from Earls, part # EAR-100192, which is a 6AN to 6AN. Like Vaughn said though: more connections more chances for leaks. I'm still weighing all the options.

 

[Jeff Clark]

I understand your concerns about the leaks. I haven't thought of any other way to do this. I'll try it and if it doesn't work, I can replace the line I splice and go back to the drawing board.

 

[sport bike]

The inside diameter of a weber fitting is . 230. The parker fitting is . 190,but can be drilled to . 325 because it,s steel. like i posted before,you would be better off putting a tee inline between the filter and the pump. Use a -6/-6/-4 adaptor or -6/-6/npt.

Vaughn, I am curious what your final solution to this problem was so I am bringing this thread back to the top.

Mag, Brandon has a solution for the test port on the hose kits. I got burned out on the hose kit stuff and turned everything over to Brandon. Anyone who is interested in a hose kit just email him--just click on this email thingy on his last post above.

Vaughn,

In your kit design you replace the lines where the steel tubing ends under cab all the way to the injection pump. I was curious why you didn't replace the whole line back to the tank with a larger diameter hose pipe (as we say here in Louisiana)?? Since the larger diameter would make it easier on the lift pump, why not go all the way?

Thanks for all your work.

yeah thats me, I'll sell the kits post part numbers, whatever you guys want

thanks for the reminder Vaughn I got to get it in the mail for you Brandon

Do you see any decrease ar increase in fuel pressure with these lines installed? Or does it even it out pre and post filter. Does any know whether it is the siphon or back pressure on the lift pump that makes it suseptible to failure. Dumb question? I don't know.

Brandon,

I have all the fittings ready to replace the fuel lines from under the cab to the injection pump. The weber carb adapters, earls#991944 came with an aluminum washer as well as a rubber oring. Do you use both or just the aluminum washer when you screw the fittings in place of the banjo bolts?? Thanks for your help.
