Spectra fuel sending unit - my experience...

All I need them to read correctly is when the gauge gets close to E

I agree, but if it reads E with 6 to 8 gallons in the tank it's kind of useless.

On an 18 gallon tank 4.5 gallons is 1/4 tank

On a 16 gallon tank 4 gallons is 1/4 tank

I would rather have a sender that reads correctly.

I just filled up my 18 gallon tank.

The gage was reading a bit over 1/4 tank and it took 13.1 gal.

13.5 would be 1/4 tank.

This is a later model (70 something) OEM sender.

Amazing how accurate they can be!
