I've been working on my dual carb setup for awhile now. Thought I would have them sorted by now. Having trouble with getting fuel to the passenger side carb. I can see the fuel going into the driver side fine but the passenger side just barely one barrel getting fuel.
I am using the Weber IDF40 carbs with a faucet electric pump. Maybe not enough fuel pressure? After the fuel filter I have a single to dual fitting to split the fuel line to the carbs. Stronger pressure to one side? Any comments would be helpful. Thanks. Dave |

That's just a temporary location for your pump right?
You can't mount a pump higher then the bottom of the tank. Pumps are made to "push" the fuel from the tank to the engine, not to pull a vacuum and especially not up hill from the tank. Also get rid of that glass filter. |
