fuel guage

[qb12]

question, my fuel guage always shows fuel on my 02 outback. however after running on saturday for about a couple of hours, sunday it took 16 gallons of gas.

is anyone have any idea as to why?

thanks...

Use the "search" feature on this board and you will find that this topic has been covered extensively. Fuel gages are just not that accurate in boats. The factory is looking for a solution, but nothing yet. Keep track of how much fuel you add and how many hours you use the boat and start tracking it that way. Good luck.

i am not so concerned about being super accurate but some movement would help me determine how much i have left.

could a fuse be out causing it to stay at full.

any idea from everyone.

These gauges tend to read empty before they actually are. If it is staying on full all the time it could possibly be grounded out. Either way you should take it to the dealer to have it checked out.

thank you or the info.


closest dealer is about 140 miles.

thanks jeff,

that is good info to have.

however i still want it to somewhat work....

These gauges are pretty simple. Does the gauge actually stay on full and not move at all?

[qb12]

wakeme,

it only moves when the ignition is turned off. other than that it says it is full all the time.

thanks for your input.

If the gauge is staying at the full mark without moving at all then you should look on the back of the gauge and make sure that the power is not grounding out. If you can, Unhook the power wire and the ground and give them power from a different source. If that gives you a diffrerent reading then thats your problem. If not, then it is either your sending unit, wire or gauge. But you can check for these other things first without taking it to the dealer.

wakeme, i will give that a try and thank you.

Actually I'm thinking that the test is if you ground the signal wire, which is the pink wire, it will cause the gauge to read full. So it is a good possibility that is the problem. Keep us posted with your progress.

wakeme,

i looked under the dash at the guage and there was a "blue" wire that was not snug on the bolt that comes off the guage. i redid that and just turned the ignition key and it went to 3/4's.

taking the boat out this weekend and we will find out. i will let you know if it works.

thank you for all your imput and enjoy your boat...

It is actually not a bad idea to check all of the wires underneath there.I have found several loose just from running normal.
