I think this is my problem. In the back of my gutted car i hear a consistant 'hmmming.' The noise only occurs when the car has been started, NOT when the battery is on. The sound seems to be brake related. Any ideas?

 

maybe your fuel pump? That goes 'hmmmmmmm' ... you'd probably hear it more too since your car is gutted

-yep, its your fuel pump

-however, if you install one of those aftermarket fuel pump
except it to be alot louder

it's aftermarket alright. i shall now enjoy my walbro fuel pump hard at work instead of worrying.

 

listen to the walbro change pitch when you hit the turnsignals of brakes.

A simple rewiring with a relay and 10 gauge wire is needed.
