OK fuel gauge worked fine last night had half a tank of gas, woke up and then it said I had a full tank. Went to the gas station, got in over 20 dollars of gas.
Drove it for over 12 hours today and it still says I got a full tank.
Now The guage is not broken becasue I put in 2 more clusters and they all read full at the end of the day.

So whats wrong here? Got H22A with walbro 255

Do I have to drop the tank? If not, how would I go about doing it?

 

to enter the fuel pump you do not have to drop the tank, you can enter it threw the back seat. remove the back part of the seat first (the one on the driver sid, then use a 10mm ranch and losen the bolt and wrestle (pull and work the bottom seat out) and the fuel tank cover should be bolt with four screw there, unscrew it and you will see all your fuel stuff......if its and eg it runs on floater so i think all you need is to replace the floater..but hit me up because my is busted too and so i need to fix mine too.
