Fuel Pump Problem
Morning all,
I have to change the fuel pump after a long running issue - its nothing flash - stock 1600 in a '72 Kombi.
The pump going in is a new Brazilian one, the changeover went OK and it started nicely when fitted. However it only ran around 2 minutes and then
died, very much like if it were starved of fuel.
I tried changing the hoses on the pump, no change. I now believe the pump isn't working. I think it ran initially with leftover fuel in the hose to
the carby but is now starved.
What I didn't notice until I pulled it back out is that the old VW pump had the pump 'tongue' protruding from the bottom of the base, where it
contacts with the rod from the block.
The new pump has the tongue slightly inside the case, I believe the rod isn't contacting the tongue enough to make the pump function.
I note the black rubber piece that sat under the original pump, like a large gasket between the pump and the body. Should I remove that so that the
pump will make contact, or will that be too much?
Pics below.
Advice appreciated, I can't get the car to a VW mechanic currently and have to fix it at home. Thanks!

You will need a longer rod

Yep, the angled pump (your old one) is used with the alternator which has the short pushrod. Your new pump is to suit a generator and requires a
longer pushrod but wiill possibly have clearance issues if you have an alternator fitted.

No problem with fit - you will need a 108mm pushrod (your old one will be only 100mm).

Thanks all, and yes its just a genny in there.
I suppose the next question is whether the pushrod is an easy job to change? Is it fitted to the mechanicals below (and therefore need an engine
pull) or does it somehow get fitted from the top?
Thanks heaps.

^^^ yep, just pull the old one out (leaving the plastic spacer block), but check the new pushrod at maximum up stroke, you want 13mm protruding from
the gasket.
