Puma fuel gauge

[Alwaysinit]

Got a puma here where the fuel gauge will drop to empty for a few minutes and then back up to where it should be. keeps doing it constantly and I wasnt overly concerned but just put 256lts into it there when the gauge was reading over half which means its not reading correct and could catch me out at some stage!
Any ideas?

Had any software updates done on it lately? Nh had a software update out which upset the fuel guage

No, hasn't had any updates.

How old? The NH software fault doesn't effect the case. The sender units are crap, the float can stick in the tube giving said fault

Not uncommon, they're a bit of a PITA! We've had software sort it out a few times, then one was incorrectly set, the last one has had a new float, still not 100% convinced it's right. Other times we've put up with it and it's sorted itself. A relatively straightforward fix but definitely a pain!

4 year old now, built in 2017.

Is it a big job replacing the float?

They managed to do it through the cab floor on our Maxxum. Can't say for a Puma but I would think they should be able to.

Puma you would have too drop the tank, but not a huge job. I would do it in a couple of hours
