Does anyone know if our old GB's use VDO or SW systems. Also does anyone have a brand and part number for the temp sender? I have the tank off the top of the engine. It is a chore to get the nuts tightened ( finally sacrificed a 1/2 inch wrench and wrench and ground it down. BTW, I bought a set of cheap wrenches at Harbor Freight for less than one wrench at the auto parts store).I hate to replace the sender on an a trial and error stab in the dark.
