    Ok so i've made my final decision. I will install the Holley Red pump in my car (sorry John).
    I have looked and can't find a good clear diagram. I would have thought that it would have been something I could find it the "Tech articles" section.
    Can any of you show me a detailed diagram?

    I see that the kits have a relay and a circuit breaker. Some have a fuse. I am not fully understanding the breaker version. Is that supposed to replace the fuse and reset when cooled down?

    yeah it'll reset itself or will have a manual reset in case of a voltage spike. i dont have one on mine, just the realy, and mine has worked just fine for over 6k miles

    You also might think of putting a switch on it. It comes in handy when working on it (and can prevent thiefs from getting far if you hide it). :rofl:

    More fuel for thought :rolleyes:. My pump is mounted by the sender unit at the tank area (on the body). I want to run my wires to the front on the drivers side but want to go directly to the battery for the elect source. I want a switch (location to be determined, around the driver side) and want it isolated from the car's origional wireing. I'm thinking I would rather use the blade inline fuse also (at the battery). The ground I assume can be at the pump area? Can I get a schematic for that from someone?

    Wouldn't be a bad idea to put a safety switch in there too, like one of these. It's standard equipment on cars with factory electric fuel pumps, and could save your car or your life in the event of a crash.

    It is not only a good idea to have a safety shut-off switch, it is required by law.
    If the car is in a collision and the engine dies with the fuel pump pumping gas everywhere it only takes a few seconds before you have died in an otherwise non-injury accident. You MUST use either an oil pressure, vacuum or inertia switch to shut the fuel off if the engine stalls. (you still have to watch for leaks from hoses and lines)

    If i'm lucky i'll flip my switch with my toung, or what ever other body part that moves LOL!.
    I could put it under my beer can holder so when the impact throws the can the gas will stop... guess I gotta get a long straw :rofl2:
    j/k...

    I think either one of those methods would classify as an INERTIA SWITCH. :biglaugh:
