Electric fuel pressure gauge.

[Don.F.Broadus at ucm.com]

The oil pressure sender is a sliding contact on a resistance element so if
you used it in a gas situation and the element failed
the potential for explosion exists. The new sensor is probably intrinsically
safe rated and a transducer type (0-5 volt or 4 to 20 MA)
to reduce the chance of explosion.  My  $.02   Don
