Hello fellow Volvo enthusiasts!
I would appreciate anyones help in this matter. Recently, I discovered a small fuel leak above the drivers side rear wheel of my 93 240 wagon. I pulled off the wheel and noticed the the rubber fuel hose from the tank to the pump was severely dry-rotted. I tried to splice and reconnect, but the hose is so far gone, it kept splitting and leaking. I need to probably change out the whole section of hose, but don't know if I need to take off the fuel tank, lower exaust assembly, etc. Is there a way to access this tank area without severe shop work or breaking something to access it? BTW, this is the second 240 wagon I've owned and want to keep it forever! Help! Please!

 

There is easy access to the fuel tank hoses from inside the trunk. It's been a while since I had a wagon but if you lift the top to storage area under the rear of the trunk there is an access panel that gets you to the top of the fuel tank where all of the hoses are attached. From there you can disconnect the old line and connect the new. Just disconnect it from the fuel pump by the rear wheel, drain the gas from the line and disconnect from the top. Nice simple 20 min job.

Good luck

 

Thank you act1292! Your recommendation was right on par and easier than I thought. Can I pick ya'lls brain with another delimma? How can I get better gas mileage from my 93 240? When I bought it a few years ago with 109k miles, I was getting about 18/25 mpg. Now, I'm lucky to get 10/15mpg. I do all the usual maintainence and use fuel additives, pfte oils, etc.,but the gas mileage suffers now at 150k and the prices at the fuel pump are killing me! Any suggestions?

 

Age should not affect your gas mileage that significantly. 18-25 mpg is about what I expect to get in mixed driving even with over 200,000 miles.

There are many items that can affect your gas mileage but I would start with checking your oxygen sensor. Basically the oxygen sensor sniffs the exhaust gas and provides feedback to the ECU which in turn will enrich or lean the mixture. Search the forum here for how to check it or better yet, buy a Bentley or Haynes manual. You will need a voltmeter as well.

Another cause can be exhaust leaks upstream of the oxygen sensor. These leaks will let in oxygen which are detected by the oxygen sensor and cause the ECU to think the engine is running lean an thus enriches the mixture.

Another cause could be a bad fuel pressure regulator. You can check this by pulling the small vacuum hose and checking for a strong gasoline smell. If you have a strong gas smell or gas drips out, the regulator is bad and should be replaced.

Of course, you should make the air filter is not clogged, plugs are clean, etc.

Good luck

 

Thank you act1292-again, you are right on point! I did a visual inspection of my exhaust system and from the muffler on back to the manifold, it has many rust holes and now that you mention this area, it has been a bit noisier than ususal. I guess now is to replace the exhaust system and see if that does the trick. Should I do anything else after the exhaust is changed that the muffler/exhaust shop would overlook-such as a pressure test, etc., or observe the fuel consumption and hope that does it? Thanks again for your insight!

 

If your oxygen sensor is screwed into this pipe, I would probably replace it as well. If it is screwed into the cat and the cat is still good, you might not have to change it. Either way I would check the oxygen sensor to make sure it is still functioning ok. Check the wires first and make sure they are still good.

Hope you get things all fixed up.
