I can't let this thread die without explaining what led to the new Carter fuel pump after having rebuilt and installed the original Bosch short fuel pump.
The reason bridges two thread categories, fuel system and non-original items. I'm getting old enough to forget things, not just long ago things, but things like what I had for breakfast. Without all the new modern bells and whistles like on my family Mercedes, I would leave the "manual" lights on in the Pagoda and run the battery down. I decided to add a "lights-on" warning chime to save the battery and my pride.
Coming back home from PUB2015, I stopped at a Radio Shack and bought a 12V chime to install during my restoration. Two weeks ago, I started installing it. I tested it using the fuse panel, and having verified that it chimes when the lights are on and the key is switched off, and stops chiming when the lights are switched off, I decided to install it in the trunk.
I hooked the chime's red wire up to the left tail lamp bulb (+) wire (light switch activated) and started to wire the chime's black and blue twisted pair up to the fuel pump (+) terminal (ignition switch activated). That's when I found the weeping leak at the terminal 0-Rings that apparently appeared while I was using the ignition switch to test the chime. That led to the week-long effort to replace the pump with the Carter P4601HP modern centrifugal pump.
Anyway, knowing how you all like photos, I have attached a photo of the completed pump (without the chime wire which is now installed as well). The pump is not as noisy as I thought it would be, probably because, in addition to the three little rubber isolation grommets between the pump and its mounting bracket, I drilled three holes in the Mercedes mounting bracket base plate, removed the three legs and installed the pump bracket to the original Mercedes mounting bracket base plate with the original rubber isolation stand-offs. That mounts the pump a little lower but appears OK relative to the ground and still provides for two rubber isolation "systems" in series. See the close-up photo of the pump mounts.
Everything works relatively quietly and I'm happy. I still have to reinstall the pump cover. I hope it will not be too much trouble to fit. It never was the original cover so if I have to modify it, too bad.
