Today was the day to get on with the EFI system

I needed to fit a lift pump to feed the swirl pot, which I fitted in the rear inner wing. This is made by webcon, and has an integral high pressure pump

The lift pump, which will "suck" was fitted to a bracket that I made and fits in snugly under the fueltank. this mounts to two existing bolt holes on a bracket, the swirl pot was fitted via rivnuts. The lift pump has a coarse filter on its input.

The same bracket holds the high pressure filter, fitted after the efi pump

 The lift pump feeds the bottom of the swirl pot, and the restricted return goes back into the top of the fuel tank

Feed to the lift pump

I then fitted the high pressure fuel regulator, with a copper pipe return to the back of the engine

I had contemplated bring the fuel lines up on the manifold side of the car - normally they run to the other, distributor side as thats where the mechanical fuel injection sits, but in the end I decided to keep to the normal fuel pipe routing, and ran two rubber hoses from the manifold fuel send and return, round the back of the engine, to the normal fuel pipe positions.

I have just about finished fitting the send and return pipes down the chassis, but I need 2 grommets to pass the fuel pipe through the floor under the fuel tank, and without these I couldn't complete the work. Once these are fitted I'll finish clipping the fuel pipe to the chassis rails, and complete the job.

Before anyone asks I have flared the ends of the copper pipe so that a good reliable seal is made to the rubber.

I need to wire up the pumps, but thats a job for when I finish the wiring
