External sump to solve starving problems
So I'm currently deciding on what way I'm gonna go with fueling my 6.0l. I can get fab work done for a decent price so I could get my factory tank baffled and have a intank pump unit retrofitted in. Only problem with this way is I have no clue on how I should baffle the tank.(any ideas?)
Now over on LS1tech theres a few of us guys talking about fuel tank mods. I'll just quote what he said.
Quote:
The rock-crawler cars with fuel injection sometimes use an external sump fed by a Delco/Carter high GPH low pressure pump, then plumb the bottom of the external sump to the high pressure fuel pump and the return to the top of the external fuel sump. At the top of the tank is a return line to the main tank, so the sump is always full.
I did the same thing on my car and my external pump is about a quart of fuel and made from a piece of aluminum pipe about 5" in diameter and a $65 low pressure boost pump from Summit. Short of rolling the car, the suction side of the fuel injection pump is always in fuel (don't ask how I know this)
It sounds overkill but maybe again its not? I think my first way to attack the fuel tank is the more suited route for me.
