Why do I have air bubbles coming from the fuel pressure check port.

What is your question?

I took the cap off the fuel pressure check port to see if it was getting fuel. I got gas and air bubbles. The motor is running very rough and is hard to start at times. Fuel pressure regulator checks good. I took off the vacuum hose and let it run 15 minutes with no sign of fuel.

you have air getting into your fuel system. this can happen with a leak in a fuel line or cap not properly closed/fail. this causes your fuel pump to work overtime and shorten its life

Take your car to a MECHANIC and get it 'scan tested' and complete fuel pressure check! That includes pressure leak down... After engine is switched off... Stop guessing!!

Thanks my friend. Don't know why I keep guessing. Guess I've got more money than brains. LOL! I've got to stop before I go broke. HA! Will have the pressure check done. I sure appreciate your input. Thanks again. Today I filled the car up and it's ran great all day. Nuts! I'm telling you!
