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 |

Crack the inlet fitting to the passenger side carb......I'm betting that you have adequate fuel there and the problem is inside that carb....
