Hi All,
2 weeks ago, I hit a big rock on the Norther state parkway. I thought the rock was going to take out the oil pan. Instead, I had an instant flat and thought I was lucky.
Today, I smell the gas fume around the rear driver side. It gets strong around the wheel well area but not so much by the main fuel pump.
What's the best way to find the leak? Jack up the car and look under with the engine running? I am not sure if the rock contribute some sort of leakage. There is no visible leak but there is strong smell.
The rock hit the rear trailing arm.
and it took out the tire.

Hi All,
FYI. It's holding well together.

Happy Sunday SB!
As you probably already know you need a new sending unit. I needed to replace mine on my 90 240 years ago. Same issue - rusted pipe. They are pricey little buggars! As I recall, it was about $95 from FCP Euro at the time. Maybe more now. If that is too pricey for you maybe you can find a used one at a boneyard or in the BB or other classifieds.
Have you already replaced your in-tank pump? Good opportunity to combine jobs here. If the pump has been done maybe replace or just check the condition of the "infamous black hose" and the mesh filter.
Good luck!
Jim

Hi Jim,
There is no reason to be sorry.
My car is 30 years old with over 300,000 miles. And I put 30,000 miles per year. It's expected and I expect more.
I am not sure if you read my other thread, I have replaced the in tank pump. I have pulled out the assembly at lest 7 times but less than 15 times. I don't remember exact number due to inhaling the gas fumes. :)
Happy Friday.

Thanks for elaborating! I didn't read your other post. Just scanned it a little.
You are a more patient man than I. 300k is when I gave up on my 90 240. The motor and tranny were still good but at that stage I grew tired of the continuous repairs.
Yeah, breathing in those gas fumes will send you to another dimension or maybe another planet!!

A few years ago, I was rolling through the backwaters of Virginia when in the middle of a sweeper a redneck retrieving a prehung door which had fallen from his F250 sans tailgate, popped up in the road. I was going about 80 and overtaking another car at the time. With Jethro and his trunk on the left and the car I was passing to the right, all I could do was to grit my teeth and roll over that doorset head on, at speed.
I stopped at the first country store to check for damage. I found none. Then the cretin in the pickup pulled in yelling about how I almost killed him. I told him if he was such a moron that he carries a load in a pickup without a tailgate and doesn't secure it, he deserves to die. About that time, the sweet little old lady who owned the store came out and said she had just called the state police. Hearing that news, Jethro disappeared.
At the next stop, I smelled gas, so I crawled under the car again, but I could not find a leak. Farther down the road, the smell of gas had not dissipated, so I did the crawl under and check thing again. About that time, my sweetheart was becoming impatient to get to the beach and said since I checked three times and found no leaks I should not worry about it. I told her, if you smell gas in a car, you got to worry about it.
When we got to the motel, I checked again, smelling gas, but not finding a leak. I knew one thing for certain: at the end of the week there was no way I wanted to drive 400 miles in a car smelling of gas.
I was lucky enough to find a guy who knew 240's inside out, Import Service in Virginia Beach. The owner/operator, Terry, checked it out and in no time found a crack in the vapor recovery line to the charcoal canister. Terry knew his stuff and his charge was fair. What more could I ask for?
After all this, if you smell gas and can't find a leak, check your vapor recovery lines.

Hi Rich,
I enjoyed reading your story.
I will go for a long drive, then put the car in jack stand, then I will search for a gas leak with the engine running. Previously, I did it with the engine not running.
As always, thank you.

Hi All,
After a high-speed driving* and make fast turns, the gas fume smell is more intense. If I drive around 55mph, the smell is "almost" unnoticeable.
On the in-tank pump assembly, does the fuel pickup tube suppose to rotate from round plate? Or fixed on the plate? I remember it was loose on the last filter change.
As always, thank you.
* That's me driving at 75mph for about 10 minutes.

Hi All,
It's much better than before but I can still smell it after sharp turns. For now, I don't feel like it's going to catch fire.
As always, thank you.

Hi All,
Thanks to my dog, he taught me how to sniff like him. I smelled the gas and saw the gas mark along the banjo fitting.
This banjo bolt was loose.
As I tightened up the bolt, a small amount of gas spewed out, see mounting bracket. I guess it was really loose.
I need to go for a long ride. I will let you know in a few days. Still, I won't say I found the problem. Haha
As always, thank you.

I recently had the exact same symptoms. Smell behind drivers door. Checked the sending unit, filler, evap. system. Ended up being a rusted out fuel filter. (may have been the original!)

Hi flood,
I changed the fuel filter but I guess it wasn't tight or loosened over time. As always, thank you.

Don't. Just use a jumper to run the pumps.

Hi Art,
That photo reminds me how I nicked the fuel filter with a pliers. The gas spewed out as soon as I started up the car. It was a heart pounding moment!
As always, thank you.

As I mentioned fred I wanted to save you from crawling under a running car. But you are already amazing welding under one, running or not. :)

Hi Art,
Thank you for your kind words. You are very generous with your praise, it wasn't a big deal and wasn't too difficult.
As always, thank you.

Tubes that come out of top of the gas tank.
No pressure to the pump.
Others that run to that charcoal canister up front
Who knows what "it" hit. On your wagon start from the Sender unit and work forward.

Hi Charles,
I checked for unusual gas line puncture or a small tear. I found it by my sniffing like a dog.
As always, thank you.

Why do those two lines run to that plastic canister below the very front of the car?

Evap canister. On line comes from the gas tank, the other goes to vac nipple. The rubber nipples on the connections often crack with age.

Now I see why I smell fuel once in a while. The line that comes from vacuum is severed, cut through by a/c belt. I need a new line. Thanks.
