Solving Fuel Smell on 924S

I have seen a number of solutions on how solve for the fuel smells. Mine are all around the fuel filler line. With no OEM replacement parts I opted to try to replace my weeping fuel filler line with a generic 1 7/8" fuel filler hose. I was not able to use the sleeves, with the hose being slightly tighter than the original. So I clamped it down, and it seemed to work curing most of the smell in the car. Until today, when I fueled up for the first time, the gas smell was overwhelming after 30 minutes.

The generic hose, while on tight, had some gas fill to just above the clamp above the fuel tank at the cut off valve, and has a slight leak right there under that clamp. I am not sure if I should try to add a second clamp above the first to try to squeeze the hose tighter at the junction of the gas tank or try to figure out how to get the sleeves to work?

I am also curious how to change the two smaller lines attached to the metal fuel filler neck. They are rotten as well, but those only give me trouble smells just at topping it off the tank. The manuals I have don't match what I am seeing when I have the carpet and cap off where the tank gauge is located. I really don't want to drop the fuel tank to get those, and would rather find what they are connected to, and run a new line by dragging a small rope to guide in the new line...

The "usual" reason you have fuel smell in the car is because you "filled" the tank and like you said "those only give me trouble smells just at topping it off the tank".

DO NOT DO THIS-until you replace the hoses on top of the tank and have the tank cracks welded on the top of the tank---only fill to 3/4.

You will not be able to use a small rope to "pull" the old lines because on one line there is a plastic vapor collector in addition to no room.

You have to drop the tank to replace the lines and weld the crack.

I do not have an answer for the 1 7/8" fuel filler hose.

If your lines are as bad as you mention, you need to replace everything from the tank to the hard line after the fuel pump.

The tank has fuel strainer/gasket-$60 that usually by now has holes in it and crud leaves the tank and is pumped to the injectors where they will clog.

The short hose from the tank to the fuel pump is next.

The hose from the fuel pump to the hard line will also be cracked and should be replaced.

In the engine bay, the fuel lines from the hard lines to the fuel rail rot.

Finally, check the short hose on the fuel rail--- the fuel line jumper---is the hose rotted at the bend inside? Do you see "wet" at the crimps?

Replace it all! Prevent an engine fire!!
