k.russell Posted January 24, 2004 Share Posted January 24, 2004 Has anyone got any photos of this pump fitted to the engine and with hoses fitted, been told i only need one return to tank, which one 🤔, front or rear, are the two stages linked 🤔 as there are two feeds from the sump, one to each stage. fitting dry sump Link to comment Share on other sites More sharing options...
Chelspeed Posted January 24, 2004 Share Posted January 24, 2004 Can't be specific about the Caterham pump. But my three stage (2 scavenge and a pressure pump) has the two scavenge pump outlets linked internally so you only have one pipe back to the tank. Put your fingers over the holes and blow into one of them, you'll soon find out which ones are linked!

Marius Posted January 24, 2004 Share Posted January 24, 2004 2 lower pipes for pick-up, one upper for return. Both stages are connected inside, so really no matter which one you go for. Caterham deliver their VX pump with the front one (the one next to the crank pulley) being blanked off and the rear one returns to the dry-sump-tank. Marius Link to comment Share on other sites More sharing options...

k.russell Posted January 25, 2004 Author Share Posted January 25, 2004 out of interest, what size of hose and fittings will i need from scav to tank(there is a 1/2"-5/8" bsp coupling in the pump) and from tank to pressure(also 1/2"-5/8" bsp coupling) I am thinking 5/8" hose and 5/8" hose tail unions, will need couplings in tank as this is -12 jic, will 5/8" be ok, sump to scav uses 3/4 hose. is it worth getting complete hoses made up, or should i use push fit. fitting dry sump Link to comment Share on other sites More sharing options...
