zardos Posted May 3, 2012 Share Posted May 3, 2012 Posted to International as it applies to many types of Land Rover. The question is, the Rover V8 EFI in tank fuel pump I believe has an in built swirl pot, is this true? Also if it has then how large is it? and does the standard fuel return to the swirl pot or tank.

Bowie69 Posted May 3, 2012 Share Posted May 3, 2012 The later ones do, yes, RRCs with plastic tank and Discos with plastic tank and the big red retaining ring. The return empties into the swirl pot. About 100mm diameter, by 150mm tall from memory Quote Link to comment Share on other sites More sharing options...
Dave W Posted May 3, 2012 Share Posted May 3, 2012 That would depend on the type of pump... The earlier types that go into a metal tank don't have a swirl pot as part of the pump, the swirl pot is built into the tank and the pump goes inside the swirl pot when it's installed. The type that is used on plastic fuel tanks (later Discos, P38s etc...) are a single unit incorporating a swirl pot as part of the pump assembly. In all cases the fuel return goes back to the swirl pot. The plastic versions have another variation (Thor engine) that doesn't have an external return pipe, the regulator is built into the pump assembly so the return is "internal" and it has a single pipe to feed the engine fuel rail.
