So I've had the Weber going for a while and overall still runs significantly better than the worn out Mikuni although not without some faults. I read about mechanical fuel pumps, the pulsing pressure, and how regulators reduce pressure as well as volume.

The issue I'm seeing is how the Spectre regulator I got has dial settings for 1-5.5psi. If I leave it on 3.5, it runs fine at low speed, but seems to have a starvation issue (if in fact this is the problem) at highway speed under load. If I nudge it up to 4, it will often diesel and appears to use more fuel (have not run the numbers yet, however). I have searched for threads like this and those seem to point at either ignition or fuel starvation. I would like to go electric either way, but this situation is a catalyst for the switch.

Question is, how did you guys go about the wiring? Did you get an aftermarket fuse block with a relay and use an existing wire for ignition source? Perhaps lengthened an existing power wire? I'm looking to get the wiring part done before I sift through the almost endless fuel pump options.

Also have a question about filtering, need one before the pump? Do you guys just keep the factory filter as well?
