Alot of people talk about hotwiring their fuel pumps. What does this mean? Do they use a stock fuel pump? I hear Walbro 340 alot.

It is basically running a larger gauge wire strait off of the alternator strait back to the fuel pump so that the pump receives a steady constant voltage. There are several electrical connectors that the factory wiring travels through on its way back to the pump, thus voltage gets lost.

It is a good idea to put in a new pump given the age of the cars in general not to mention the benefit of increased flow. Both mods are very easy to do and can be done in a couple of hours.

It is a must to have your fuel system running tip-top before any other performance mods.

Racetronix seems to have the best deal on the pump + hotwire kit:

Im sure it requires dropping the fuel tank and from what you were saying its not hard to do?
