<VV> gas tank sender question (All corvair content for a change)

[Larry Forman]

Hi Mike,
It sure sounds like you have a hole in your sender and it sinks to EMPTY when installed rather than float upward.  Did you remove the float and see if it really floated.  One quick check is to immerse it into a pan of warm or hot water and GENTLY squeeze the float and see if any bubbles come out.  Also when removed from a tank of gasoline, any cracks might still appear wet as the gas evaporates.  But I like the immersion test better.

The Earlies read 60 ohms at full and the Lates read 90 ohms at full.  Proportionately less toward empty.  Lew Young in CA rebuilds the Lates.  He is an UltraVan officer.  Do a search for him at the CORSA directory or VV or check with UltraVan people.  I think Lew completely rebuilds these for about $50 each and they look like new.
