Could anybody tell me the best way to calibrate the sending unit to the fuel gauge on a 71 scamp,I have tried twice but can't seem to get it right,any help would be appreciated
I may try the unit from year 1,like you I won't be able to install until spring,hopefully this will fix the problem,will post again when I find outI just located a nos sending unit, issue is the guy wants an arm & leg for it. I may bite the bullet on it to see if it solves the issue. I wont get a chance to put it in till spring, so I'm hoping someone finds a cheaper fix in the mean time.
Agreed,it would save a lot of time,work and headaches,not to mention a lot of moneyToo bad the vendors won't put the time into building a quality sending unit. The units in the past were. Shouldn't have to calibrate them or try to make them work. That should be done at the factory. Just lazy.
Not a trick question,I have tried bending the float arm,and tried bending the stop tabs.No matter what I do it always shows half a tank off.It could be I got a hold of a bad sender.I tested the gauge and it is good,checked wiring from gauge to tank,all good,it's been a pure headache.I always bend the sendin unit arm. Is this a trick question?
Thanks I will double check thatYou need to make sure your sending unit reads the same ohms full and empty that the gauge does. Sounds like there is a mismatch.

I did everything you suggested but I didn't have any help,I tried to watch the gauge as I moved the float arm,at the angle I was sitting I may have been looking at the gauge wrong,I will try it again but with help this time.Thanks for the input,I will try again soon.What I do is test them before installing in the tank. I hook it up to the connector at the tank and ground it. I have someone watch the gauge as I slowly run it through it's range. Start at the FULL position, stop at 3/4, then 1/2, then 1/4 and finally at EMPTY. Then I check by gauge position and note where the float arm is when the gauge reads FULL, 3/4,1/2,1/4 and finally EMPTY. It is amazing to see how bad some sending units are. It's putsy work, but beats installing it and finding out it's junk.
