Just wondering if anyone can give me a little advice.
I have a 2 litre '77 bay. The fuel pump is leaking & has been for some time. I have tried just tightening the screws but it is still leaking. I can't track down any rebuild kits & everyone I speak to suggests changing to electric. What I wanted to know is
1. How does the electric pump work (i know how a pump works but) the mechanical pump is attached to the motor & obviously as revs increase the actuating arm increases speed thus increasing output. How does this work with the electric pump?
2. Does anybody have any recommendations. 2 litre fully rebuilt with cam & crank grind only & stock twin solexes.
3. Any idea on costs ?
4. Has anyone attempted cutting their own new gasket for mechanical fuel pump.
Any advise would be appreciated.
Thanks guys & girls.
I'd just be replacing the stocko one. Easy and does the job for stock and near-stock engines
BUT because you asked, an electric pump always delivers too much fuel and must be 'governed' with an in-line fuel pressure regulator. The mechanical pump, as you know, delivers fuel in relation to engine speed

Hi
As VWcool said, but an electric pump in a Kombi can sometimes lead to the fuel tank syphoning into the sump. Stick with the stock one.

I'd be happy to stick with the stock one guys, but I can't get a gasket kit anywhere & it leaks like a sieve.
How about mail order from Micks Motors, or Vintage VW Suplies or Classic?

Already done all that. Most people I have spoken with just say it's a no go, change to electric. I'm going to try ring Westcoast on Tuesday morning ( Monday afternoon for them ) to see if they have them. It's in their catalogue but when you try & enter it into the shopping cart it won't work. With my past experiences with them the code doesn't work for a reason, incorrect pricing or no longer available.
I have also heard that rebuild kits are no longer available. New Brazilian pumps might be available, although they are sealed and can't be rebuilt (once worn out). If you have an original german pump, don't chuck it whatever you do, I was told.
Sorry, not much help ey?

I replaced my mechanical pump with a Carter P60430 Electric Fuel Pump. No problems so far but it's only been a few thousand km. I left the mech pump to block the hole.
I have wired the Carter via a relay that connects to the alternator light wire. This means that the pump will stop if the engine does which is handy if you're in an accident!
my 1.8 runs better than it ever did since installing an electric pump. It was a very simple one afternoon procedure. My brazilian mechanical did not last very long at all, and hated high temperatures from the begning.
go elec never any bother tell the mob how you buy of what its for and they should set ya straight i have run an elec pump on me old vw for years no worries and no pressure regulater
