Hi all,
I'm fitting a 1UZFE into an old Lotus - the car did not have fuel injection before the engine swap. The engine is fitted in the chassis.
I'm trying to get my head round the fuel system. I've tried searching the forum but couldn't find the answers. Has anyone got experience of fitting the 1UZFE into a car that didn't have fuel injection?
I've seen some designs that use 2 fuel pumps, a low pressure one in the boot and a swirl pot and high pressure fuel pump in the engine bay, 4 connections on the swirl pot, to and from the fuel rail, and to and from the tank.
I've also seen a design where the return off the fuel rail is plugged up (blocked off) and a single high pressure pump is fitted in the boot with a regulator, and the regulator is providing the fuel rail pressure, and the return to the tank is via the regulator. Then a single fuel line is run under the car, to the fuel rail input.
Does anyone know if the latter design will work with the 1UZFE? Or which would be better - or more importantly - safer???
Does anyone have any diagrams of the standard Soarer fuel system?
Any suggestions or advice appreciated.
Cheers, Mat.
