Thanks alot for your help!

But It has the eletrical pump fitted to the LH side under the tank and found the eletrical wires going to ut but just no power. Currently it is running on the camshaft pump but wanted to convert it to an electric pump and it has everything just bo power to the fuse.

Hi, i found the wires but i had no luck with power. Ground is good but there is no 12v coming in from the green wire. I checked fuse number 11 and no power aswell but the relay has all 4 from 5 12v so the relay is good. Any knowledge why is this ? And fuse is new.

Ok thankyou that helps alot. I have an m10b16 carburated not fuel injection but it doesn't have a fuel regulator. Is that normal or i need to fit one ? (Attached is a picture of the cap) Thankyou in advance!

When i removed the cap i only found the fuel level gauge but there are fuel pipes like the previous picture but i cant find where the wireing is. I only can see the leveller wires. My question is where i can trace the +ve wire that goes to the external pump. Thankyou in advance for your help!

Hi I'm new to the e30s and i have the same problem but i can't figure out how to get access to the wires where they connect to the internal fuel pump as its not working, i need to check for connection as i jumped my external fuel pump and it worked and i even checked my relay and fuse which are both...
