Hey guys, I'm going to be running 2 Carter/Weber carbs on my Offy intake on my 51 Plymouth. Will be running on the original 218 flathead six. What I need to know ASAP, is where the hell do you guys get your fuel line, fittings, and a junction block to split off the line from the fuel pump to 2 carbs. I went to my local NAPA, and the guys told me that people haven't run multiple carbs since the 70's and it couldn't be done. I laughed and walked out. (If it isn't in the computer, they can't help you) If you guys could help me out...what is the thread size of the fittings as well? I need this setup: fitting at (stock) fuel pump -> hard line -> fitting at junction block ->junction block -> 2 fittings -> 2 hard lines to carbs -> 2 fittings at carbs Anybody know the thread size of the fuel pump, and of the Carter/Webers? I also saw a pic on here awhile ago of somebody running dual carbs that had a fuel junction block with a small pressure gauge on it that was really cool. Any idea where to get that? Thanks for the help!
Break up the issues...simple first issue is to find the fitting or adaptor plus fitting needed to install steel tube into carb inlet. This will require one of three starting points: An old and knowledgable counter person (good luck!) A counterperson who will let you rummage in Weatherhead cabinet til you find something A junkyard fitting from whatever used those carbs as OEM to be compared with parts store fittings. Once you can get something that installs tubing into carb, getting a Tee fitting to connect three tubes will be easy. That system will be built from readily available brake stuff. Extra issues will arise if said tubing is metric. What do those carbs come from?
Several ways to do it yourself. Easiest is a brass T fitting with NPT threads. You can buy brass hose barb fittings in the size hose you want and in the NPT size you want. The hoses support the 'fuel block.' Another way is to saw a piece of aluminum round, drill and tap for desired fittings and drill for hold down bolts. Look close and you'll see a dual fitting block on the workbench. The fuel log in this pic is round aluminum, through drilled in a lathe. Disregard the curved piece of stainless braided hose - its just lying there. If you make a shorter one it can be easily drilled sitting vertical in a drill press. Using square or rectangular block aluminum makes a nice fuel block. Just depends on what you want and how much of a hurry you're in....
Thanks for the tips guys. Ok found it and ordered from Jegs: I'll run rubber fuel line for now to get the car up and running, and switch to hard line at some point.
