Truck Still Earns its Keep
Quick set of words about the Spectra FG33C sender that I put in my Spectra 38 Gallon tank.
Short version: It works
Long version:
I'm working on my 1994 with a flatbed and conveniently a gooseneck hitch/door that puts me right at the sender.
It is a sender made for the OBS (and maybe '87 and up??) gas trucks. It has 4 prongs instead of two; two are for the sender, two are for the gasser in tank fuel pump. Pay no attention to the two extra plugs for the pump. You don't need em on your diezel truk. The plastic surrounding the plug seeds to be massaged so the 2 prong plug can fit. One of those fuel pump prongs also need to be cut.
Bracketry exists for that aforementioned fuel pump; ignore it, you dont need it.
Take the float arm off and do your best to make it read F to E in this massive tank. Without making a new arm success may be limited, but you can get close with what was provided.
"Duck Bill" red rubber thing on the return line will likely hit your float sender arm if you choose to bend yours like I did. Use some common sense, cut the 90 degree bend off the tube and make it not hit.
I used Gates 27097 submersible fuel line with a brass barb on the end to get to the sump in the tank. It fit perfectly, the barb was sitting right in the indented sump with no modification.
Other than plugging it in and installing the lock ring etc thats about it. Surprised me with how easy it was. Took maybe an hour, and admittedly this is my first time ever doing one.
More pics: I got my tank out of a 1986 parts truck so it had a bullnose style sender that the previous owner had put together. It read my 1994 gauge backwards . But it gave me a great idea on what geometry I needed to have to get the pickup and float close to right.
