    in tank fuel line

    Anyone tried to use Summit's fuel hose inside the fuel tank? Thought I'd try it out and see how it holds up. I have about 18" of 3/8" hose inside the tank coming from each Bosch pump going to a bulkhead fitting. I know there are better quality hoses out there, just thought I'd be the guinea pig.

    Red, Is it too much work/expense to eliminate it, to avoid worrying about it? With welded-in-place(or not)thickwall aluminum tubing maybe, or? Yes-No?

    due to the design of the GMT900 fuel pump assembly it was going to be pretty much impossible in my world to do the fittings in the top of the fuel assembly for two pumps, these damn pump assemblies look like something you'd pick up at walmart in the toy section(all plastic). I put two -8 bulkhead fittings through the top of the fuel tank and ran hoses to them from the pumps. I actually am only running one pump for now until I get some fuel rails that are designed for the truck intake or I go ahead and swap over to a car, LS2, intake from my old setup. I tried to use the LS2 rails on the truck but it put the seals in such a bind that they leaked like a sieve.
