I've been running a walbro 255 hanging on the inner frame feeding my classic FAST system since 2009. While most of my driving is around town, I've done long trips including all day Power Tour runs. Haven't killed the pump yet. 100% stock pick up set up and OEM vapor return line as the return puts the fuel in the corner of the tank. This is not a quiet setup, but it was simple and effective. I just don't ever run the tank down to empty.

I'm confused as to why any EFI car would still be using the ballast resistor, unless you're still using the orange box? I use the starter solenoid as a power distribution center with a relay triggered by the ign circuit.
