[diesel_mercedes] Re: Fuel guage Maladies , Cures & Service

 

Tony ;

You'll be pleased to know that the sender comes out the trap door underneath the fist aid kits tray . no need to drop the fuel tank for any service .

However , don't go yanking it just yet , instead go buy some Startron at the boat store and does it 3oz. per fillup and soon you'll see the results .

The sender is designed inside a tube that slowly drains as a method of damping (preventing wild swings of the gauge needle over bumps)  and if you get any fungus growing in there it slows then stops working completely .

In the end , I had to carefully remove my sender (beware smelly fuel drips on the carpet & seat back) and unscrew the bottom plate then hand clean the accumulated black gooey mess before my gauge worked properly but since then no troubles .

We're in Wa. State and there are some W-123's about , mostly in very good nick .

Doing fine, on our trip will spend the night in Missoula MT, and should be home in our own rack tomorrow.

Buuuut, we filled the fuel tank the other day and the guage stayed at the full mark even after 400 miles. The guage looks good, goes to zero when we shut off the key. My thinking is that the float is stuck inside the tank, does anyone know if this happens, and if so is there any tips on unsticking the float? Really don't want to drop the tank, and don't want to guess about the fuel level. Will the warning light come on regardless of float position? so many questions so little time.

PS a lovely 300 SD flashed past us, north bound on I15 south of SLC yesterday any one here?
