Hi
I was wondering if I use a twin fuel pipe under seat fuel pump for a m52 engine on a m10 car?
Also do I need to reroute pipes and change anything? Obviously the car is a carburettor model with a external fuel pump, so do I remove the external fuel pump and change the pipework setup?
Also do I need to run mew electrical cables from the fuel pump relay to fuel pump and how is the cable routed?
Thanks

Whether you can use your existing tank depends on if it has the cup fitted which the pick up of the electric pump fits in, otherwise you will have fuel surge problems.
Only pump on a carb. model is a mechanical one on the engine, so obviously that'll be removed along with the old engine.
Whether the fuel pump wiring is there depends on the age of your car. Lift up the rear seat cushion and find the multi pin plug and socket on the RH side. If this has a green/purple wire going to it, then the signs are good. I very much doubt if the loom going on from the connector and going down through the seat pan has the green/purple though, so you will need a replacement loom for that.
