Weber 32/36

[geezer101]

The Weber requires a lower fuel pressure than the Mikuni to operate. High fuel pressure will cause flooding and affect how the truck runs. If I recall correctly the mechanical pump runs 6-9 psi of fuel pressure and the max needed for the Weber is 3-5 psi. The fender mounted "fuel filter" is a recirculation cannister - you should notice an inline fuel filter before the mechanical fuel pump. Now the recirculation cannister may very well be enough to drop fuel supply to the carb to overcome the potential high pressure issue. If it's running right and the only problem you have is a leaking mechanical pump (which is a bad problem to start off with) I'd have a tendency to think you may not need to go electric with a regulator.

*side note - if your recirculation cannister is a metal one, be warned. They have the potential to rust out. There are plastic cased units but I think it's going to be a scrounge through a JY to find one...

I thought it was an odd filter and it is in fact metal. I think the pump was leaking when I bought it since the area under it is free of oil =). It may just be leaking more now due to more back pressure with the weber.

I will probably go ahead and just get the electric pump and regulator. The truck will be used infrequently so I wanted to do as little as possible to make it run. paid 500 for it and the weber/tabs has already doubled that.

Thanks for the info.
