On a trip recently, the petrol gauge on my Cabrio, which has never been very accurate, suddenly registered empty. I knew this was not the case, as I had only recently filled the tank. When I got home, I emptied the boot, and inspected the sender (not an easy job). To my surprise, there was no arm on the sender and no float. I tried to find both items with a piece of wire, with no success. I decided to "bite the bullet and emptied the tank and it took out. (An even harder job). Eventually I found both items.
There was nothing to stop the arm sliding out of the housing on the sender, but with some thin thread & super glue I devised a way to secure the arm. Before doing so, I decided to tackle the problem of the inaccurate reading. Speaking to Mike Garner, who was in touch about some brake binding problems, he suggested that the vertical lift of the float should be the same as the depth of the tank. I made some calculations and decided that the arm was really double the length it should be, so I cut a fair bit off the arm. I then secured the arm and replaced everything.
I now have a petrol gauge that makes accurate readings, whereas before it read "3/4 full" when I filled the tank and I never really knew when I was approaching empty, filling the tank before I really needed to "to be safe".
The question remains.....why didn't Marlin do this when they fitted the servo and sold me the kit...or at least told be how to make the adjustment?
