...or else it will one day leave a puddle on the ground and you'll have to deal with it ASAP.

I've had this car nearly 10 years and have put about 110,000 miles on it. I've never touched the fuel filter until today. It rusted through. 1992....240,600 miles...don't know if/when it was ever replaced previously.

Luckily I had all the parts ready to go. Didn't end up needing the transfer pipe, the old one didn't break, although it took a lot of back and forth with the impact gun to free the banjo bolt from the inlet. Always be prepared. If you have an old 240 with a crusty old pump & filter, you should have this stuff on the shelf.

Those brass fittings with the hard plastic line can be reused or salvaged by scraping the plastic line off with a sharp knife and using regular high pressure fuel line and hose clamps. There's regular barbs under there. Also a good way to delete the outside fuel pump and keep the filter stock.
 
Good catch. Glad nothing worse happened. Those genuine parts sure last a long time. At least 10 years ago they still did.

I just found out about a friend whos 940t just burnt up due to a fuel leak. So you just can't ignore it when the gas smell is bad.
 
Wow!
Other than being rusty, I'm sure some filters completely clog up on the inside, especially with bad fuel.

I don't usually watch a lot of his videos, but Chrisfix did an interesting video where he cut some fuel filters open and the old one was really bad inside, so the first thing I did was change the filter lol.

For those interested, here's the video:

My Lumina had 390 when it rusted in half original filter surprised it never rusted out..but the same thing happened my 240

That new filter I just put on has been in my possession for....over 10 years? I guess it's possible for the paper element to have broken down but no dust or anything, and it was capped with plastic and looked good.

I came back home from lunch yesterday and smelled gas. Thought maybe it was from the charcoal canister. I noticed it near the front of the car. Didn't notice any leaks on the floor under the engine, popped the hood, no obvious signs of fuel. Then I came back out around 4pm and the garage smelled of gas. Found the small spot under the main pump. Fuel leak trumps all other plans. Dropped the fuel pump / filter tray and both were damp, but the filter was so rusty that I figured it had started leaking. Was glad it wasn't the pump or any of the lines.

I used an impact to remove the banjo bolts. First one on the inlet stuck, started to rotate the banjo fitting and twist the short piece of fuel line, so I went back and forth til it finally broke loose. Gas looked black coming out of the filter. Way overdue for changing.

Car runs about the same. I recently turned the boost up with a ball & spring MBC. 15g, 3" downpipe, 2.5"-back (F+T). Pulls pretty strong from 2,000 rpm for only ~10psi, but still a little knock around torque peak.

Now I can feel better about swapping in my cleaned injectors. :nod:

I can't recall, but isn't there a hex portion you can hold on to so the banjo bolt doesn't spin and snap that fuel line, or is it perfectly round? Perhaps some decent pliers could grip it..

FWIW, I have always used an impact to break that banjo bolt loose. It is much easier than fighting it with hand tools IMO.

Stock LH2.4? I am on stock boost on a +t and used to get some audible knock and peak boost until LH richened it up. But ever since I switched to Mobil fuel instead of QT, car seems much happier. Could also be the fact that I might have been running 9-10psi instead of 6-7..idunno.
 
I never replaced the one on my wagon because I never had flow problems.. Cut it out for the banjo fitting (Which was too rusty to reuse) and I could feel the element banging around inside when I shook it.

I think it's round. You can kind of see it in the first picture above. Hex on the filter body and the nut, but banjo is round. Bolt/washer/banjo/washer/filter all stuck together so it all tried to rotate together. :e-shrug: The other side didn't really twist much. Didn't help that I had an 18mm socket on a rusty 17mm banjo. I had to pick the scale off the flats of the banjo bolt to get the 17mm socket on...but then it was fine.

I never considered wrenches to take it apart. I did use wrenches to put it back together. 17mm / 22mm on one end and 19mm / 27mm on the other. Was glad to have a set of BIG wrenches for the 27mm that I've never used before.

Stock...chipped fuel ECU. I've considered unplugging the ECU and seeing if it will change anything when it "re-learns". But overall, I can't complain.
