Fuel pump mod

most relays operate on ±10% as far as i know. The closer the voltage is to the rating, the more reliable it will be.

ok... dumb question number 1.... Razz

With the relay setup on the fuel system...

does the supraforums version of bridging the wires still have to be ASWELL?

or would i just use the relay??

someone helps! Razz

The relay method is REALLY easy. Just take your time, measure up the wires to the correct length and be sure to solder them or use the correct joins.

OK so instead of a Green wire and a black/red stripe wire i have a green with pink dot and a fatter pink/cream wire next to it. The fuel controllers are the same part number so im assuming these wires are the same thing yeah?

OK so im still slowly draining the battery somehow. Ive pulled out the relay so if i dont drain it then i know it's definately that, but how could i slowly be draining the batt after doing this mod? Bad earth? Poor solder? Any ideas?

To drain the battery I'm guessing there must be something using constant voltage, so you may have to check the wiring to your head unit, etc if you haven't already.

Or your battery could be stuffed but I presume you would have checked this

Yeah i thought this too, this problem has only come about since i did the 12v mod. I havent touched anything else electric in the car.

I should note that overnight the car is fine to start, but give it 2-3 days of sitting around and it's low and un-startable Razz
