Right-o! A new day, a new problem, a new thread. Actually two problems...

Hi!

I got an electrical petrol pump and blocked the hole where the mechanical one used to go. For the new pump - where is the current supposed to come from? I'm not sure which wire I'm supposed to use. The wiring diagram for my car (I think it's the right diagram) in the haynes book doesn't have an entry for "Fuel Pump".

The pump doesn't stop pumping when the float chamber is full, so I wonder: Is there supposed to be a return valve of some sort on the float or an inline bypass on the fuel hose? Or does it just pump and let the float deal with it?

Also, the distributor was not tightened properly, and it swivelled a bit. Now I have turned it so that the car starts, but it runs very roughly. I want to start the car, and then while it's running, turn the distributor until it's running smoother... but when I grab the dist.cap, it shocks the heck out of me.

Where could it be wrong? I only touch the plastic/rubber parts, but still it jolts me :/

Thanks!!!

hi, on the petrol pump side i have a facet pump on mine and without a fuel regulator the pump will just keep pumping fuel into the carb and flood it, is it running rich? and does it over run sometimes when you turn the engine off?..as for wiring it up i had mine wired into the ignition so when the ignition is turned on the fuel pump starts before engine starts and the earth just goes to the body..however im going to wire mine upto a switch aswell for that rally feel...forgot to say the fuel regulator goes in between the fuel pump and carb and this will stop your carb from overfilling/flooding..i got mine off ebay under filter king fuel regulator,also has a fuel filter combined in it..hope this helped

cheers james
