Hi Ray, Doc here. First of all what year is your "Z"? If it is an early one then I highly suggest that you run a separate circuit to feed the electric fuel pump. If you tie into the circuit that you described then you stand a chance of overloading it and loosing the turn signals and the fuel pump. A simple fuse holder with the 15 amp fuse will surely suffice the be the feed supply for the Holley Monster pump. You may want to rubber mount the pump to isolate the sound some, for a more pleasant driving experience. I hope that this helps you.............

Hi ZDoc,
I'm hoping to get a second opinion on an electrical question. I've installed a Holley electric fuel pump back by the gas tank and need a 12v, ignition switch enabled source, capable of providing 7.5 amps (the size fuse the pump calls for) My thinking is if I attach to the wire for the ign lead of the voltage regulator it will give me a 20amp, fused source that wont have power with the key in the acc position.

As best as I can tell from the factory service manual the only other thing that line is used for is some guages and the turn signal circuit. That would also give me a voltage source close to the oil pressure safety switch for the pump. There will also be a 7.5 amp inline fuse in the wire from the safety switch to the fuel pump. Any thoughts before I try to burn up my wiring harness :)

Thanks for your help on the crankcase vent/PCV valve stuff. Once I did a little research and learned exactly how a PCV valve works it all made alot more sense. I had done almost exactly what you described in your last e-mail with the exception that I screwed the PCV valve into a pipe thread to hose fitting and used a regular hose T in the brake booster line. That
way I could leave the PCV valve on the end of the factory style braided hose and didn't have to figure out another way to go from the 1" pipe from the engine down to the 5/8" (?) connection on the PCV valve.

Thanks Again,
