This is an idea I had a few years back but never had the need to try it out. I was able to rebuild both my senders.

Recently, a couple guys tried it on FB and it works so I decided to document it.

If I were to do it, I would eliminate all the extra fittings but I included them in the infographic for guys who want an easy solution. You could cut off the flares, remove the nuts, put a partial flare on the tube to act as a barb and use hose clamps instead.

Spectra FG05F may work out better for external fuel pumps.

The fg03-f sending unit doesn't list an OHM range, the other one the 05 list a 0 to 95 ohms. Hbody gauges and most aftermarket gm replacement gauges are 0-90 ohms.
What's that going to do to the gauge reading accuracy?

They are both zero to 95 and should read very close to the OEM unit.

5/95= 5.3%

You could always adjust the reading by bending the float rod if desired.
