Re: gas tank & gauge help

It seems like all the earlier GM tank senders had a five hole mounting flange that uses a cork gasket to seal. The later 90 ohm senders install with an oring and a retaining ring.

The holy grail here would be a 30 ohm sender on the later oring flange. I can't find such an animal . If anybody has I'd sure like to hear about it.

I'm pretty goosey about modifying something that carries electricity and operates inside a fuel tank. Tanks Inc has an the flanges I'll need to have a good shot at a leak free installation
