Hi,
I suppose I can now claim to be a real SU family member as I have seen my carbs pouring gas onto my exhaust... Great experience indeed! But I don't wan't to drive 50 miles back home like this. The car is now stuck in the countryside.

I've read what I found on the forum using the search, & I dont understand what I could have done wrong. I'm running a B20B with freshly rebuilt SU's (Except rebushing) & a Pierburg pump (Probably aftermarket since I got it on a B18A)with DIY pre-pump filter. I don't suspect my brand new float valves to be leaking. The bowls are clean. Fuel comes out of BOTH vent holes. So I'm suspecting the pump is at fault.

I tried to softly hit the pump wit a screswdriver, which made the leak stop for a few minutes (even at higher revs). It came back after a while when idling. I'm planning to mount another (used) fuel pump to at least drive te car home, assuming the pump is putting to much pressure on the line. Has this happened before to some Pierburged cars? George seemed to be a Pierburg/SU combination fan in one of the posts I read, & fo the last K miles miles I agreed. So can a pump all of a sudden increase its pressure or is there anything I forgot to think of & will make my efforts useless? Should I bring something else with me on my "bring the car home" operation?

Thanks for your help!
