Replaced the Holley 1945 one bbl on my 84 Dodge Ram 150 3.7 engine. I believe am having problems with vacuum. The truck is idling fine, but when you step on the gas it stumbles. The diagram under the hood is to vague. I need a vacuum routing diagram that is more detailed. Where can I find this?

It is very likely that the vacuum hoses are the problem. The only people that have a manual with the diagram you need is a dodge dealer, contact the service dept at your local dealer and they will probably photo copy you a diagram from the service manual.

I was going to include a vacuum diagram but I need size of engine, weather it Federal or California if it has ESA, High Altitude and Heavy Duty Cycle. Maybe the diagram I have is different than yours. They don't make it easy that's for sure. The bowl vent will be on top of the fuel bowl and about 3/8 inch it's a big one and goes to the vapor canister. The vacuum hose for the EGR valve goes from EGR to a vacuum solenoid and from there to a Ventura vacuum port. Which is a vacuum source that has vacuum that starts at part throttle and drops off about ¾ throttle.
