    Check out the Mallory pumps, they are a gear type pump and generate the least amount of noise.

    I am a advocate of using the RX-7 pump. I have used one for years with good results on my Z. I am running SUs and the pump puts out 5psi. and so far I haven't had any trouble with the extra pound of pressure. We tried one on my friend's engine with triple mikuni's and it fed them just fine . The pump is quiet and if mounted with rubber you cannot hear it going when the engine is running. Bone-yard prices $15.00 . Mount it back by the tank and use a in line filter between it and the tank. I did add a pressure switch on my oil sender port so that the pump only runs when there is over 7psi oil pressure. Otherwise on a 240 the pump will run as long as the key is on. If you crash this could be a big problem. Gary

    I had triples on a '72 with a Holley pump and it was LOUD. After I sold the car, the new owner swapped it out because he couldn't take the noise. I think he went back to a mechanical pump and has been very happy.
