Default 964 C4 fuel leak

Hi All

hoping someone can give me some leads, I have a 1990 964 C4 in Australia however work overseas and go home 2 to 3 times a year, my son starts the car but doesnít drive it. I was back over Xmas for short period and didnít drive it but on last last before departing put a new cover on it and started it. After a minute I could smell fuel also noticed gauge was low anyway stepped out off car noticed fuel leaking from bottom around middle of car behind front wheels?
I turned it off washed down as was around 38 deg C but didnít get a chance to lift it see where leak was coming from, any ideas what may be the cause?
Appreciate and clues if anyone experienced this when Iím back next will put it on ramps and try to identify where itís leaking.

I have seen it leak from the fitting going to the fuel pump and the fuel tank, what I have done before is cut the crimp part off with a drimell and use a clamp instead fairly easy to do.

Good luck

I concur that the leak is probably from a fuel pump fitting, either a hose or also check the high pressure fittings too. Easy to do once the car is lifted.

Not sure why the car needs to be started if you're not planning to drive it. It serves no benefit and in the air cooled cars can lead to premature wear. I'd just plug in a batter charger and leave it alone. IMHO...

Check the banjo fitting on the fuel pump. May just have to be tightened. If you have to replace anything, either drain the tank, or clamp off the hose. Be careful with sparks, hot drop light etc... around gas.
