Re: fuel filter having air bubbles

Is your fuel system pressurising properly? i.e. does the fuel cap still go pffffst when you open it after priming the fuel pump, even if the car has been sitting for a while? If so then it could just be a minor fuel leak at the filter itself, it's probably not blowing air just small amounts of fuel. There isn't really a way to get air in the system unless fuel is coming out somewhere, is it leaking anywhere else? Check the washers on the filter too, the stock ones are aluminium and will crush a little when tightened, most aftermarket ones are copper and need to be tightened more to stop them from leaking.

Re: fuel filter having air bubbles

Yes it does in fact,I was away from the house for a while i came back,before i change the old fuel filter and notice that the fuel bubbles coming out..and I was away for 4 days..
So I could have a fuel leak somewhere,I heard my fuel prime and notice it was spraying also..
So I could have a fuel leak in the fuel line somewhere..
Darn it how does this happened I haven't drove this car in 3 yrs!!

To quote the great Michael Ironside (from a movie that for all intents and purposes doesn't exist), "Ashes to ashes, dust to dust. If you don't take it out and use it, it is going to rust." Unfortunately cars continue to rot even when they're just sitting around minding their own business (actually especially so).

If you do have a leak then there could be a small weep in one of the rubber hoses, I doubt it would be in a hard line but it is possible. Trace the lines from the tank to the fuel rail and see if it looks wet or stained anywhere. Where was it spraying from? The filter? If you only just changed the filter then I'd really be looking at that banjo bolt to make sure it's tight. Take it out and see if it is damaged. Check out those washers too, did you use new ones or re-use the old ones? Lastly, is the filter seated properly? If the lines have to twist even a little to fit on then that could be creating the issue.

Re: fuel filter having air bubbles

In you other post about "No Fuel To The Rail", I thought you said the hose that connects the Fuel Pump Assembly to the car had a leak and you were going to look for a replacement, or use that banjo bolt replacement part from AZ and some fuel line and make a replacement.

Re: fuel filter having air bubbles

Ya that car has been sitting for a long long time..
Okay I will defiantly look at the fuel line diagram and check for any wet spot on the fuel lines..
I heard the spraying when I heard the fuel pump prime..and the fuel filter was bubbling and spraying on both fuel lines and the banjo bolt was tight..
I will look at the banjo bolt to check for any damage,the fuel filter washers were new and the filter..the filter was seated properly also..

Re: fuel filter having air bubbles

Tone meister it wasn't any of the fuel pump assembly,but i might be wrong,because when i replace the fuel drain washer from honda there is no leak now when I turn the car on..
So I will defiantly trace the fuel lines..
