fuel filter 480

ebdl · Jul 19th, 2006, 22:30

The 480 forum seems to be down at the moment, so hopefully someone here can help.

I've been having some trouble with a fuel leak, which I finally traced to the pipe between the fuel filter and the pump/sender unit. Unfortunately this pipe is a real swine to remove. Volvo, in their wisdom, decided to use some screw-shut unions which seem resistant to removal. This may be useful if you want to avoid your pipes coming undone accidentally, but it's a real pain in the arse if you actually want to take them off.

The fuel gauge sender end of the pipe resisted being undone so well that my attempts to turn the union resulted in the plastic of the sender breaking. I have new sender. Unfortunately I am having a similar problem at the fuel filter end of the pipe. This suffers even more for being exposed to all the road muck a car picks up in 110,000 miles.

Does anyone have any advice on an effective way of getting these unions undone? At the moment I am considering simply replacing every pipe in the system as it will be easier and involve much less cursing, but obviously more expense.

Please help, my sanity is at risk.

Thanks, Ed
