sending unit solution

[weldvair@embarqmail.]

I bought dolphin gauges where the gas tank sending unit is 90 ohms instead of the 30 ohms used in a 1968 c10.

I am looking for a solution that does not require welding on the tank.

Has anyone removed the movable float part of the new sending unit & attached it to the 1968 sending unit thus keeping the original gas tube...
if so how did you do it

Thanks
