Anyone using an electric fuel pump with a Weber???

My Weber 32/36 takes forever to start my CJ. I have to crank it for 25-40 seconds before I can get the engine to turn over. Is anyone using an electric fuel pump to run their Weber? I assume that this would eliminate the cranking because the fuel would be available immediately. There may also be something wrong with my carb, but it has always been like this. If the Jeep sits for a week I end up cranking in short intervals for a couple of minutes. We have discussed this issue before and I don't know if it is possible to get a electric pump that would work with the 2.5lb fuel pressure regulator.

Later,

I have the same problem with the weber on my YJ. An elecric would be great but I would keep the engine driven pump if at all possible so you have a "hot spare".

Re: Anyone using an electric fuel pump with a Weber???

I had this problem with my Weber. I also participated in the discussion here earlier. To recap, here's what I suspect is causing this problem.
#1. Improper positioning of fuel filter causes carb bowl to siphon off through the return line. Most of us should be running the 3 port filter with the off-set return nipple at the highest point.
#2. Mechanical fuel pump. This could also be the culprit. I suspect it has an integral check valve to prevent fuel from draining down the supply lines back to the tank, however, I couldn't get any details on this.
I tried a new mechanical pump, (mine was the original one) and it cured my problems.
