i'm personally not using one, but a friend is in a 72 chevelle. so he should make sure the tank outlet is higher. does the fuel line going thru the frame help, as it is lower? a lot of the circle track guys have them about the same level in the alchohol classes.

One thing you have to remember is that a positive displacment pump is not a sucker, it's designed to push fuel. Sure it has some suction due to the vacuum created in the fuel line, that's why most people run front mounted fuel cells on drag cars, and even then they are mounted with the bottom of the tank close to the fuel pump level.
On the round racers, if you're talking about sprint cars, their tanks are mounted high and most of them drive the pump off the back of the cam.

the roundy cars i'm refering to is the wissota late models and mods. the fuel pump is belt drive on the front of the engine, just like an alt. some of the tanks are mounted low, others high. also, are all belt pumps "pushers" or is there a way to tell if they suck the fuel. asking these ? as i don't want my friends engine to run bad from lack of fuel. also need to know to defend the reasoning to the guys at the shop where he is building the car. these guys have been racing wissota classes in huron,sd for quite a few years using this type of fuel system. and i don't think they are the only ones.

The Hilborn,Enderle, and Rons are, i can't speak for the others. One thing else is that these guys may be feeding them with an electric pump mounted back near the tank which will usually work especially with a carb.

thanks for the ideas, gonna take a closer look at his setup and the late model beside it and ask more ? from them to see why it is set up the way it is. also, should it have an internal or external bypass, and what kind of regulators for each.
