What kind of improved gas mileage can I expect from a Howell EFI system on my 76 coach with a 455 and a quadrajet?

Went and did my normal pre drive check. No brake lights. Found that the issue was the 39 year old brake light switch. Replaced that switch. Headed off to Elkhart. The Howell EFI worked PERFECTLY all the way. Great mileage. Got to within 45 miles of the GMCMI rally. The new brake light switch from China failed. Oh well. Got 500 miles out of it. Went to lower the right rear air bags to take a shower. T then the two compressor system quit working. Then during the night. Our furnace stopped working. I expected some of this because this GMC sat next to a cornfield in Iowa from Oct of 1995 to Oct of 2015. But now it appears that I've pissed off the electrical god EL. That has to be my problem.
