Fuel Leak
LukeV85 - February 4th, 2008 at 11:03 PM

advice needed!!!

went to start up my bug this arvo, and car would not start.

When round back to check out the engine and could smell fuel. Opened rear bonnet to find fuel leaking onto other fuel lines. It seemed to be comming from the carby, near where the choke is located.

Any ideas, im pretty sure its not a fuel line, as they are brand new.

Reminds me of 3 Bugs I looked at while in the market to buy (out of about 10) recently of which leaked fuel.
One was from the fuel pump to carby (car dealer, rough as guts..the dealer that is..) another one was leaking from the fuel pump on the top right side of carby and the 3 rd one leaked fuel from porous fuel lines (very old).

After seeing all this I went and replaced all the fuel lines on my new 71 Supabug after getting her home as sure enough all were shot and while I was under there I added a fuel filter (mounted it above LH axle near air vent).

The reason your Bug may not start could be because of a flooding engine in which case your fuel leak may be caused by the float valve needle not seating because of crud between them? The beast have a fuel filter fitted?Worth a look..

Take the air filter off
careful as it has oil in it...

and look down the barrel of the carby while someone turns the engine over
if You see fuel pouring in there, its the needle and seat in the carby leaking..
it should seal when the carby if full...

if You have a fuel tap
turn the fuel off.... 45 degrees... or about 2pm

then see if the engine starts...
the way to start a flooded engine is to hold the pedal to the floor until it starts...

it won't start if the fuel continues to pour into the engine

but once its flooded and the petrol turned off
hold the pedal to the floor and keep turning it over until the engine starts...

best of luck

I just reread your post

You have a leak on the RHS of the carby near the electric choke...

well it could be the needle and seat are sticking
allowing the fuel bowl to overflow
and for some reason ?? the fuel is leaking from the fuel bowl lid or top...??

do You have hose clamps on Your hoses??
