I have looked around the site and haven't been able to find the answer I am looking for. My Riv's fuel pump is working fine, but the dash gauge is not reading correct, sometimes reads correct down to half a tank, but then fluctuates back to full. I already checked source voltage and verified ground at the pump harness. Has someone else had this problem in the past? I know I would have to pull the pump/sender, not that big of deal, I just wondering if anyone has repaired the sender to function correctly again, or is it just a better idea to buy a new pump unit for $300+ ? Thanks for any help!
