New guy here, so by way of introduction I thought I'd provide a link for anyone that's interested in a Weber conversion. Here's my complete conversion -- start to finish!

Mazda Mikuni/Solex carburetor -- Weber conversion; DONE!! - The Garage Gazette

Hope it helps a few folks out.

The Weber kit I used is from eBay -- just search the following ...

MITSUBISHI DODGE D50 RAM50 WEBER 32/36 DFEV CARB E. CHOKE CONVERSION KIT W K614

Specifics --
Truck: 1988 B2600 4x4
Vendor: webercarbsdirect
Price:$269

 

BTW -- after my second in-tank fuel pump failed around 35K miles, I left the old in-tank pump in place and just plumbed in an external electric pump using the existing "hot" "gnd" wires from the in-tank pump. The old pump was never removed and it has never been a problem for the new external pump. The new pump just sucks the fuel through the old pump.

The truck has run over 200K miles with that pump and it feeds the new Weber flawlessly at 4-6 psi

NICE JOB! Original was vaccuum line hell!

2 different kits? Diff carb #'s but both work.
