Sending units on 2006 30 spectre??
 

Hello spectre people.

I've got an 06 30 spectre that's almost done getting rigged with 300r's.

I've got an issue with the fuel sending units i believe and it's been this way since I bought the boat.

Guages read correctly when full but once they get to around 3/4 tank they both go from reading to showing empty and don't read again until I fill it back up.

My questions are

Does this sound like an issue with the sending units and if so, where are those things?? I've been crawling into the boat and even had a performance shop try and find them with no luck

There are small half round plastic covers by the outside front edge of the rear seat. Under that cover is the sending unit. Mine was an 8" WEMA sender. This was the setup on my 2006 30.

It's been a while so don't quote me, but I believe if you disconnect the sender from the gauge and then ground the gauge, it should jump to full if working correctly.
