On any car or engine, you can always start at the fuel injector or carbourator and follow the line leading to it backwards till you find any part of the fuel system your looking for, including modified ones. This should only take a few minutes and has the advantage of exposing any other things (like pressure regulators, etc) also in the system that may have caused a problem. Uh...this also works from the gas tank and following it forward...or anywhere along the system you want to start! True, if it's in the fuel tank, (generally more true for fuel pumps than filters), you'll end up, by elimination, isolating it to having to be there. Generally accessed by a removable panel somewhere on it, and frequently hidden under the rear seat.

siphon It out with a cut garden hose..
Believe it or not it's inside the gas tank.

The simpliest answer is to check the fuel filter. It may be starving the engine. Lets enough gas through to idle but not to run under load.
