Fuel Sending Units

[Jack15T]

Hi Folks, I have a 71 K20 pickup with factory or dealer installed saddle tanks. They are the same ones listed in the factory assembly manual. I am looking for two fuel senders for these tanks. The left and right are identical. The only markings on the senders state 90 OHMS and Travel Accessories. No serial or part numbers that I can find. I will try and attach a picture of one. The tanks are 10 inches deep and the fuel sending unit is also 10 inches with the rubber hose on the end. It rests on the bottom of the tank. The mounting flange is a 5 hole. If anybody has a source for these or something that would work I would appreciate any info. Thanks, Jack
