Fuel Systems?

Im going to be in the market for a new fuel system soon...

The choices that apear to me off the bat are FASS and Airdog, what I am looking for here is a death match. Post any thoughts, proof or not. Or any other companies that offer the same type of system.

Do you have a regulated return and the intank mods done? I would start there.

Other then that, I have no comments on the fass vs airdog part.....

Just a basic 01 F350 CCLB SRW -Good from a far but far from good

Don't do two stock pumps. It will not work, what will happen is one pump will get damaged. Because what you will be doing is the first pump would be trying to push fuel through the second one.

Pumps are regulated for a certain out put pressure. So doubling the pumps will not raise the pressure. You would need a fuel pump that is regulated for a higher fuel pressure.

Your idea may actually cause worse or poor fuel supply to the engine.

I wasnt thinking of putting them in-line because that would just make high pressure for longer distance, but yet parallel pumps. split the line from the tank to 2 pumps then back 2 one. to meet the demand of the injectors at WOT

There are a few setups like this floating around. I will be doing this and putting an airdog between the pumps and tank.
