Rallye lift pump wanted

[Hoppum]

As above, need the Rallye lift pump and fuel level assembly as I’m converting my syncro to an injection engine.

Thanks.

If it’s any help, I used a 2wd gti lift pump, which fitted onto the syncro fuel pipe/sender unit. Has worked fine for the last four years. All I had to do was drill a small hole in the cover for the power feed to the pump, and seal around the wire.

That sounds a good idea!

btw the actual pump is the same unit as fitted to the Rallye.

That was my next plan of action if one didn’t show up, got a spare 2wd assembly at the ready, would be nice to have the proper item though.

if you have a carb’ed engine, you don’t have a lift pump in the tank, and you can’t fit an electrical one unless you get the whole setup with pump etc

the carb don’t have fuel return, and only a 2 prong connector on the liftpump lid

but its all the same on all MK2 syncro with injection engines

If you have a Syncro Carburettor tank unit & want to run injection.

You will need a 2wd injection in tank unit (complete)
from which you use the tank fitting & fuel pump.

From the Syncro carb unit you use the fuel gauge sender & pick up depth piece, which you modify by fitting the electric fuel pump & strainer, Just make sure the final depth is the same as the carb unit.

ive got complete rallye tank with rallye pump and sender in…. spare

My syncro’s (carb 1.8l GU) tank fitting had a feed and return on it, but the return pipe was 6mm o.d. as opposed to the 8mm o.d. of the kjet injection tank fitting fuel return pipe.

I used the injection return pipe from the metering head all the way back, as it was the correct length. It has the same i.d. as the feed line, i.e. 8mm, so it was loose on the tank fitting return pipe. I made a shim out of a 1″ section of the old carb 6mm i.d. return line. A little heat softened it enough to slide on, and gave the larger injection return line something to tighten down onto.

I was worried slightly that this would restrict the flow of fuel back to the tank, and lead to excessive system pressure, but it checks out at 5.7 bar (correct for later kjet systems) and runs just fine.

Do you need an inline pump with the rallye tank or is it high pressure aswell as lift? If not what fwd pumps you lot using? Is it k jet stuff?

[Chris S]

Yes, you do need an under floor in line high pressure pump as well as the low pressure in tank pump.

[mike671]

Got on etka earlier just to look at system so it’s all basically k jet stuff if anyone has a rallye lift pump I’m interested…

[Hoppum]

Still needed .
