I am having problems of air bubbles in fuel pump bowl. Engine is running rough and sluggish. How can I get rid of the air in the line?

Stormy...The first thing I would check is the sediment bowl to make certain it is tight againt the gasket above. Then, check the rubber fuel flex line that attaches to the fuel pump. Overtime they develope little holes and suck air. Good Luck, Pat

You are getting air from someplace between the fuel bowl and the gas tank. Do you have any connections in the fuel line? Check those for tightness. Are you sure that your fuel line is in good shape? Is your fuel bowl missing or have a damaged cork gasket? Those are all places I would check. And no doubt your rough running will fix itself when you find the air leak.

We often find that the rubber parts of the fuel line were not alcohol proof, and have developed almost invisible cracks. I had this happen on one of my own cars. Be sure that the fuel pump is likewise fuel proof if it is an older unit. If you have rubber hose in any part of the system, be sure that hose barbs were used wherever there is a joint with a metal line, and use worm screw hose clamps as the spring type typically leak air into the system. These places cause fuel starvation of the type you mention.

Thanks for the input. I will start checking all connections as soon as this cold front move thru and will give all feedback.
