How does the fuel filter come off?

Hello,

I have a '92 240 that I bought for my kid's 1st car. It has 162K and is a nice solid Volvo. I'm doing the usual fluid / filter changes I do when I by any used car. I have some questions.

I've tried to get the fuel filter off. With it mounted on rubber stand offs like it is I can't crack loose the connections. I use two wrenches, one for the filter and one for the fitting, but laying on a garage floor with the vehicle jacked up, the plate with the 2nd pump and filter on it pulls off the rubbers mounts and is all over the place. I can't get any leverage. Talking the lower mounting plate off the body and leaving everything hang on the hoses to do it causes the same problem. How can I securely fasten or block the filter so it stays still to crack the fittings loose? Is there a trick?

What kind on hoses are used between the 2nd pump and the filter and the filter going toward the engine compartment? I may have overstressed the pump side one and should replace it.

Thank you and thanks for this site.

Mark

Can't anybody help me with the fuel filter removal problem?

When I replaced the main (undercar) fuel pump on my 1986 740 GLE last year, I seem to recall that the pump and filter were both mounted in the cradle. I removed the suction line from the pump, the discharge line from the filter and removed the cradle with pump and filter as one assembly. Yours may be similar. I would think that if you put one open end wrench on the filter housing and another open end wrench on the discharge coupling, you should be able to get leverage between the two wrenches. I hope this helps. One more thing, disconnect the fuel line at the tank sender unit before you break loose the filter connections. Otherwise, you siphon the remaining contents of your tank onto the ground.

By the way, since you are replacing the main fuel filter, I would suggest pulling your sending unit out of the tank and inspecting the in-tank pump and pick up filter sock. The filter socks in the tank tend to deteriorate over time and these things are not routinely replaced as part of a normal service. Once a hole develops in this filter sock, dirt and debris in the fuel will foul both the in-tank and undercar pumps, causing the in-tank pump to freeze and blown the fuse, and fouling of the main fuel pump causing either failure or intermittant starting problems. Look at this if you haven't done so already. You can search this forum for my experiences on this topic.

Good luck with your new-to-you Volvo and let us know if you have questions.

Thanks for the reply. I pretty much tried that. I took the car to a Volvo refurbishing garage with reasonable rates. He looked the car over and said it was in very good shape except for a bushing going bad in the tail of the transmittion. I'll have him do the filter for me when he does the trans. and concentrate on other stuff.
