Fuel Sender Question - Journey 258 (2008)

[GradyJ258]

I recently filled up the aux and part of the main tanks and went out for a 4 day trip to our cabin (boat access only). We need to cross 30 miles/50 kilometers of semi-open ocean to get to our cabin and I ran on aux to get there. Upon returning and using my main tank I noticed that the gauge was flashing at one bar - there should have been over 40 gallons/160 liters more in the tanks (when I completed the return leg). I played with the sender and ground and they looked good. So I ordered a new sender form Wema (not yet received) and went and filled up the main tank. The tank reading was working again - thus I was either siphoned or the fuel sender is 'sticky'. If siphoned I ould have gotten into a lot of trouble if I ran out of gas in th e30 mile crossing (experiencing 4'-6' seas) (I will ensure I check my guages before I leave next time) (I am also religous about tracking purchased and spent fuel so I know that I am correct on the expected amount of gas in the tanks).

Does anyone know if the fuel sender on a 2008 Grady White fuel tank is susceptible to being 'sticky'? Or did I just get robbed! Anyone who would have puled up to our private dock in the middle of the night would have to have large kahuna's (given the geographical features in the area (lots of hiden rocks, etc)). I don't know anything about the fuel sender construciton so I thought I would reach out to the forum.

Thanks - David

I just changed my sender. mainly because i lost trust in it. got the same readings as before, so i prob should trust it. If its the reed type its unlikely to stick. if its the float type its possible but not likely. I removed my sender and manually moved the float to verify that the gauge and wires were ok. Plus its a definitive check for half/full / quarter readings. Unfortunately, people will go to any length to steal from you today. I work in that environment every day. Its really sad. Its also likely, someone who you know.

you should make sure you don’t have leak also. probably would smell it but you never know for sure.

not much help, but that all i have. :sorry

They aren't typically accurate....if your motor(s) are 2008 vintage then you can get fuel consumption data on your multifunction screen via NMEA 2000. Use the gallons burned to have a better idea of how much fuel you have.

My last two GWs would get to one bar pretty quickly...stay there for what seemed like forever...then once the one bar started blinking you we're down to fumes.

I bought WEMA replacement and when I took out the Royce Industries sender there was a loose magenta attached to the sender unit (at the bottom). I am not sure where the rest of the pastil/magnet part was but I must say my 2008 tank was spotless with zero sludge! I checked and the WEMA sender is not magnetic so I am not too concerned if there is a plastic / magnetic part floating around (I hope!). Anyway, WEMA customer service was excellent!
