I have checked fuel pump delivery and it is very good, plenty of pressure/flow

I fitted a larger than normal fuel filter and my possible fuel starvation went away.

Would water in the carb float bowl from the tank create the ilusion of starvation?...misfire... cutting out

reason, we ran the engine with the pump disconected and collected the petrol in a jug, to my amazement there was about 200mls of water in the half liter of fuel pumped out :shock:

Which begs the question...how much is in the tank?

can I drain it (the tank)

last week I threw away the replies to my post of 2 years ago. My symptoms were very lumpy running and inability to pull. I am sure water in fuel was one of the suggestions. Somebody else had a similar problem but only after washing the van. I think it was suggested that a hole in the filler tube would let water into the tank.

As mentioned above I fitted a bigger filter & re-roted my fuel lines and my problems went away.

You are correct of course
I think I'd like to get to the bottom of it though.

Is water ingress to the tank a probability from say... jet washers? Heavey rain, fords, puddles etc

Yes, the tank being U shaped could collect dirt and muck in the channel, this could allow the tank to rot out, allowing water in.
The rubber grommit bit that the filler pipe goes through to get into the tank could be perished? this would allow water that has sprayed up from the wheel to run into the tank.
The rubber sleeve just behind the filler cap perishes easily and could allow water in, but I cant imagine it would let much in unless it is a very bad state but I think you'd have noticed when filler her up.

I believe not. If you are getting strong pongs then ideally you need to drop the tank and replace all the grommets, pipes and that rubber sleeve at the top.
Thats on the list for mine, JK do all the grommets.

Yes.

One way of clearing the odd bit of muck out of a jet of a fixed jet carb is to take the air filter off and whilst revving up block the choke inlet with flat of hand.. depending what rev-band the engine is going throuhg at the time, the suction often pulls the muck out or dislodges it... won't work with a bowl full of water though.
