fuel tank sending unit

The tank is rectangular, doesnt seem to matter if running or not, the sending unit is mounted midship,It doesnt have a mech read,with a conventional sending unit you can bend arm to adjust but this one has me wondering if it was any good from the start all connections are proper. CC there is no float arm on this unitit kinda like a post with a float that runs up and down tank size is 24"x60"x8" an exact copy of original

I would email or call SP ...especially since its only a year old .... That sender almost sounds like the one I was describing ....

SPTanks installed an electric sending unit in the tank they built for me. It was a reccommended upgrade. I haven't had a chance to use it yet.

I'd call SP in a minute too. But I also plan to install a fuel flow meter. I don't trust the gas guage in my truck!

I feel your pain. Last year I installed a new sending unit into my sceptre, and it doesn’t work. Unfortunately, the screws holding mine in place are just about stripped out. I’m not going to open that can of worms. I’ll be installing a fuel flow meter that Santa gave me.

Regarding your problem, I’d think that most of the sending units are a resistive type, and you could check it out with a volt meter. Call SP, and ask about the type of output. If resistive, ask them how many ohms it should be when full & empty. The gauge may not be compatible, or it may need to be tweaked
