Aeroquip fuel line journey notes...

[Chas]

I have always had a fuel pressure "problem". by problem i mean after i installed a pressure gauge , it seemed to vary from 3 to 6 to 4 to 5...kinda see the overall picture yet?
So i decided to go ahead and install the Aeroquip fuel line.
I swapped the Holley carb that was leaking with a Edelbrock Performer series carb to match the intake manifold last summer.... when i purchased it the sales rep told me i should regulate the pressure down for the Edelbrock, as they only require 4 to 6 lbs , and the holley was probably 9 or so...and it could damage the jets....i passed on the regulator, and told him i would install the gauge to see if the after market mechanical pump was doing that much pressure...it wasnt , so i didnt get the regulator.the pump lost the decal , but it resembles a holley .
so fast forward to today....i fired it up with the new fuel line, all the fittings and elbows in place....now i have 9 lbs of pressure...constantly...so i ended up installing a regulator...now im at 6 lbs and its very consistant....and when i shut it off the pressure dont seem to drop either.
the most important thing i learned is how to cut the braided wire covered hose...what a hassle...the way i learned to do it was to use a good boxing tape...and use a thin cutoff wheel , like i use to cut off old bolts with..and cut thru the taped area leaving some on each end of the hose....it zipped right thru the hose and left the end pretty clean to work with.
i would urge anyone to use this setup if your concerned with pressure or leaking....its sealed and has no obstruction on any on the hose...it looks real sweet also!I will post a pic when i get the chance...

That's exactly the way we do it at the factory. I work for Eaton who now owns the Aeroquip name.

Thanks...

It took me awhile to figure it out but it does the trick.Chas

Vettedude,


I spoke with my employer's patent lawyer, and he advised that I could share my idea for a braided line cutting tool since the idea has been in the public domain for over a year...so here it is.

Basically, make the tool about 4" long so that it fits in the jaws of a work bench vice. The thickness depends on the type of hose you plan to cut, but the design accomodates easily two different diameters. The height is also dependent in the type of hose you plan to cut. I made the prototype in wood, and it worked great. Then I made it of aluminum alloy, but it is not idiot-proof that it will stand the friction of a hacksaw when the person keeps cutting even though the hose is cut....:L...so stainless is best.

One could make it with only one slit across two different diameters, but the way shown in the drawing makes the tool more resilient to withstand the shear force created by the contact of the hacksaw with the braided hose. I also recommend that the diameter channels for the hose be made a few thousends of an inch smaller that the hose diameter to help keep the braided strands tightly in place while cutting. The roll pin helps keep the two halves properly aligned. Fit the roll pin to one side and a matching hole on the other.

Today, the stainless version still serves us well. Enjoy

I ran with the Aeroquip fittings and aluminum line on my 1978 TPI. It made the most sense in terms of the plumbing for a custom EFI set up. I used the socketless hose instead of braided. The cost was the biggest factor- the socketless is so much cheaper and if you buy it with enough length you'll have plenty to last a while!

I'd recomend using the AN fittings to anyone who is willing to upgrade to a worry free connector. I can't stand the brass fittings. I have never had success with them.

The -6 AN fittings went on so easy and were dead on reliable. A little expensive in the begining, but no problems for three years!
