Fuel Pump Wiring

[Carl Beck]

Carl, my May 1972 build '72 240z has the in-line fuse holder for the fuel pump.

Hi Bo:

That wouldn't surprise me - my 11/71 build 72 Model Year has one too. I put it there when I switched to an electric pump - VBG -

Are you still running the mechanical pump on the engine as well?

The engine still had the mechanical pump installed and no electric fuel pump. The wires by the gas tank are there still taped up. My in-line fuse holder was taped up as well with the correctly colored wires.

Enrique,

Thanks for the pics..Mine is still taped to the harness with blue tape, but now I know what to plug into and where to wire the fuse...

My '73 is a late build date 8/73 . The in line fuse holder on mine failed when my old pump locked up and shorted out . The fuse didn't blow, it melted . If it wasn't for the pressure switch that I have in place , Earlier posting look back to #4 , I would most likely have severely damaged the wiring, or had a fire. In my attempt in restarting and or figuring out what had happened . Power would have still been on to the pump. My new fuse holder now has a 15 amp fuse and I have had no further trouble and of course a new pump. Gary

Thanks alot for the pics, I found the fuse right away, right we're your pic showed it. I'm pulling my L24 motor and tranny this weekend, to figure out where the coolant leak was coming from. Hoping for just a bad head gasket, fingers crossed.

I've decided to rebuild the motor even though it has very low miles, and I'm just looking to build a nice, quick (but not a race car), mostly original, and (hopefully) very reliable 240. I'm gonna do the rebuild myself. I've rebuilt motors before, but this will be my first overhead cam motor. Previous experience was with American muscle cars.

I bought a set of round tops on eBay, and put the original flat tops and the smog stuff in storage. I'm just looking for a slight bump in performance (nothing extreme like a cam), and it seems like 2.5" exhaust, electronic ignition and a good carb rebuild should get me there.

I've only been on this site since I bought the car 2 weeks ago, but I think this question may open up some debate. Again thinking of reliability as the top priority and speed and HP as a distant second, what would you folks suggest as the best way to make modest performance gains, without sacrificing driveability or reliability? Just to set a budget, lets say I want to sink less than $1,000 into the engine.
