My 79 E25+ has a simple pneumatic fuel gauge made by Marcra Manufacturing of Costa Mesa California. I have no idea if it was original. I finally got it plumbed up with some 1/16" tubing but I can't get it to the zero and span set. I can only get about 30% pointer travel as i move the tubing from the top of a full tank to the bottom. There are two adjustment screws but fiddling with them hasn't helped much.
Wondering if anyone is familiar with setting these up or has useful documentation. I've had no luck searching for Marcra Mfg.
I like the simplicity of it and will be disappointed to replace it with an electric system.
