Thanks for the reply - the reason I asked is that fuel is pouring out of my carb at the inlet and I wondered if a faulty fuel pump would cause too much pressure and cause this?Speedy Jim said:Essentially, yes.
When the pushrod rises, it compresses a spring in the pump.
As the rod lowers, the spring is free to drive the pump diaphragm
and create pressure. If there is nowhere for the fuel to go,
the spring/diaphragm merely keeps pressure against the static fuel
and no real "pumping" occurs.
Hi, I haven't been doing much work on the beetle recently and so haven't been on much. Things are okay though.yellow_spider said:Hi Des , not seen you on the forum for a while , hows it going ?
Just a random thought but could the float valve be jammed open (in the carb) causing it to overflow externally ?
Yeah and I've noticed you're selling the very stuff I need. I have replaced the fuel hose now but just the bit from the fuel pump to the carb. This seemed to solve the problem. The car is booked into the garage for a full service on Tuesday - I have been using it everyday and don't have the time to do anything with it myself at the moment. When it comes out of the garage I'll mail you if I am changing the rest of the fuel hose - it would seem wise to since this has happened.Moby5153 said:Don't forget you have some cash on the slate Des.
