Not if you get the right one - you can get them down to 1 1/2 psi.

Sorting the original fuel pump can take time and take you away from other tasks. If it were me I would but a low pressure electric on from Ebay - about $30 so the engine will run and come back to the original pump when the vehicle gets on the road - then keep the newer pump as a spare.

When we last got Ricks Series 1 going the pump needed a helping hand/mouth. Basically, it needed priming. Once primed it ran very well. We were the supervisors. We let Rick suck the first load!

That's what we (he) did. Disconnect the pipe from the tank at the pump end and loosen the pipe at the carby. Get the pump running. Suck until there is fuel at the top of the pipe. Quickly attach it to the working pump and, hopefully see a squirt of fuel at the carb.

do it the easy way, stuff a rag with a air duster in it into the filler cap and gently preessurise the tank

Where's the fun in that?

cheers

Cheers Dave,

forgive my ignorance (and I have lots of it!) I thought that these pumps usually were meant to be installed at lower than the sitting fuel level...

is that the case, if so where is a good spot to mount on an 80" that wont get wiped out?

I have no idea what PSI the Series 1 32 Solex runs at but you can get the cheap electronic pumps at varying flow rates and varying pressures.

The one I have on my Haflinger runs at 1.5-2 psi. It ran a 34 Solex I had on it OK and the current twin throat Zenith quite well.
