Anybody running an external fuel pump with a single Tillotson Carb?



If so how do you modify the carb to run with the external pump? Remove all of the guts except for the round diaphragm with the metal circle?

Will a pump like this work with the carb or will it flood out? Thanks.

Does your engine have some where you can get pulse? The old Tollotson carbs had the vacuum pulse running through the carb manafold. Other than that I think you just need to remove the fuel pump stack.

I tried it with my 74 yamaha. It had a keihin diaphragm carb and I hooked up a mikuni pump like u showed. It didn't work well for me so I ended up getting a mikuni carb instead and it works. U will have to play with jetting though.
