My fuel pump has been playing up for a few days and has left me stranded for hours untill it got going. The fellow at the local workshop recommended I try pulling out the fuel pump and cleaning out the dirt from inside. My question is... how do you pull out the cables attached to the fuel pump.? There are two at one end, and a circuit connected in behind. I had a go at the cables but they're hard to remove, and I can barely even get at the circuit connection.
