temp sender

[tripster]

I have an 89 comp with the 351 PCM. The motor was modified before I bought it. The intake manifold was changed and now requires a 1/4" temp sender. It has ford logo forged on the intake. I am having a hard time finding the correct temp sender with the correct ohm rating. The boat does have the original temp gauge. All input is greatly appreciated.

Thanks
