Re: Need to calibrate sending unit in fuel tank!
 

Thanks,

I probably won't mess with. It's hard to describe, but it seems that after
fill up after fill up that the " Reserve" volume is increasing. When it was
first installed there was just over 2 gallons approx. at empty. Now theres
between 3 1/2 to 4 gallons left. Trust me I love having the extra fuel as a
reserve, but if this is increasing I would like to know why?

Re: Need to calibrate sending unit in fuel tank!
 

How does it read when full? Does it fall off after just a dozen or so
miles? IMHO, empty and 2 gallons out of 15 left would be OK, that's like
13%, but 4 out of 15 is over 25%. I would want my gauge to say almost 1/4
at 4 out of 15. If you want to adjust it, you have to remove the sender and
bend the arm that holds the float down a bit, so it's closer to the bottom
of the tank at rest (empty). With nearly 4 gallons at empty, it gives you a
false sense of hope and you will push it.... and push it... I don't want
insurrance (I pay too much for that already), I want to know exactly how
much is left!

Re: Need to calibrate sending unit in fuel tank!
 

Hmm. 4 gals. on 15 would be too much on E. Two would be perfect. Just
out of curiousity, why did you go with a 15 instead of a 20 gal.
replacement?
