Fuel Line questions
OK, maybe my previous title was bad....Has anyone either done, or have reasons against running braided (Aeroquip) fuel line from the tank to a Holley mechanical fuel pump.
I can't imagine 5-7psi sucking a good hose flat but maybe I'm wrong????
Anyone?
Thanks.

Re: Fuel Line questions (tshort)
Is it ever bad to upgrade ? I think not. Go for it but if you are gonna replace the line from front to back use a larger diameter line. Increased volume is a good thing :smash: :cool:

Re: Fuel Line questions (One GM A Tech)
I was thinking about this too.
The previous owner ran a segment of rubber line between the steel line from the tank and the steel line under the passenger door. It is clamped but started leaking at the clamp when I jacked up the rear. (A new clamp fixed that)
I need to replace it with either new rubber, or new steel, but I like the braided idea if it works. :)

Re: Fuel Line questions (tshort)
I considered doing the same thing.
I spoke to the tech guys at Summit and they said it was doable but I was going to have to weld one of the braided line fittings to the tank sending unit. I dont weld, not to mention when I added up the cost of the aeroquip lines and fittings I was looking at $$$$$. I went with the steel lines and am using the $ elsewhere. The steel lines went in with no problems. Took some patience, but after my Trailing arm bolts this was a piece of cake. Another alternative, if you are going for the braided line look, just get the braided "Pump to Q-Jet" Kit from Summit. This is an area where you will actually be able to see the fancy tube. Afterall, you cant admire the braided lines when they are under the car anyway.

Re: Fuel Line questions (Stewart's74)
I'm not wanting to do this because of the "cool" factor, I just don't see how you can route that long-a## hard line with the body still on.

Re: Fuel Line questions (tshort)
tshort: You have to understand that the negative chi toward braided lines doesn't have anything to do with failure, especially not sucking the line flat, I personally guarantee that won't happen. It mainly has to do with the internal friction of the line, and there being a slightly greater pressure drop than with a hardline. Some people are also afraid of braided getting cut. I'm going to go with -8 (with 2 barbed fittings in the tank) all the way for my 454.

Re: Fuel Line questions (tshort)
Travis,
Routing the tube up and around the rear kick up area is really quite easy. Here's what I did.
Removed old lines carefully so I would have a template to compare the bends. Began to feed the new line up from under the vehicle towards the rear kick up. Put gradual bends in the tube as you snake it through and before you know it youre done. I also bought some extra tube so I could "practice with it. Worked great and looks as good as new.

Re: Fuel Line questions (Stewart's74)
Stew, did you use steel tubing or aluminum tubing? Aluminum is probably easier to bend, but is more prone to cracking and metal fatigue over long runs. Just wondering what type of line people were using.

Re: Fuel Line questions (Smokehouse69)
Smokehouse69,
I used steel. Also, one thing I failed to mention before. I did it in 2 sections and used a compression fitting to attach the 2 pcs.

Re: Fuel Line questions (Smokehouse69)
Good suggestion Stew, but then there's an added cost of tubing bender and flaring tool. Right?
So, from what I'm gathering, both will work....steel/aluminum will have less fluid resistance, "arguably" more protected, and possibly cheaper. Braided hoses are much easier to install, (and hey, nascar uses them :) ).
