fuel sending unit

[radiocom]

Hello, I have a 1981 Brave that is on a chevy p30 chassis and has a 70 gal tank. I need a fuel sending unit but cannot find one local or on internet. Will a 40 gal work? my 70 gal looks just 2x as long as a 40 but not sure. I have seen 60 gal diesel units but not for 70 gas. Any help is appreciated.

That might be a "Tuffy" to figure out...First of all IF the depth of the tank (40/70) is about the same thats a good start.

Any baffles blocking the swing arm OR just maybe the replacement unit has pretty close measurements to the original.

What holds the new sender/pickup tube to the tank (locking ring or screwed down).

P-30 Chebby's use a 0-90 ohm resistance sending unit, One good thang is you can calibrate your new unit once all of the measurements are known.

My new (PITA) 80 gallon tank took a little work to calibrate along with the (NEW) Stewart fuel gauge but is on the money (10 gal) 1/8 tank...20 gal 1/4 tank and so on........

I guess you will just drop the tank and yank the unit and search around for the unit that is close for your needs

0 ohms is empty & 90 ohms is full, Good luck.

Stewart warner makers and markets replacement fuel gage sender units. It is the depth of the tank rather than the capacity that is important when ordering from them. I used one of their units in my Foretravel. Any auto parts store that handles Stewart Warner equipment can get them.

Thanks for the replies. I think I may search for school bus tanks and parts. What is the unit# of the universal or adjustable SW sending gauge?
Thanx again

Summitracing.com will show the different gauges.
