Hey Jared, welcome to Epic Marine! Hope you've had a chance to poke around the site, lot's of stuff here. And very knowledgeable, resourceful, helpful people.
Our '99 e22 fuel gauge is doing the same thing right now. We'll probably end up replacing it at some point. Our boat's on at least the 2nd complete set of gauges, and now they're starting to fail again. Gauges for all boat manufacturers struggle with this particular design; Toyota didn't manufacture them. I think Medallion did.
Capt Rick sells them on the site under "Buy Parts" near the top of the page (assuming y'all have early model dash - '99) ~$100 + $15 shipping for fuel gauge (MGA0010917), See Figure 15, Meter, Switch. If later dash (
>'00), then 4 in 1 for ~$240 + $15 shipping (MGA0011519). If there's a price by something, then Capt probably has it in stock. The MDC (early) or MMDC (late) is under Figure 10, Electrical Component. Send Rick a PM.
When we bought the boat ~2007, none of the gauges worked; except for the hour meter portion only of the tachometer - but not the tachometer itself. Ended up buying a new MDC (computer under dash for gauges), fuel, 2 speedometers, oil pressure, water temperature, tachometer (the hour meter started all over again at 0), volt, etc. Probably cost $800-900, but sure was nice having an idea what's happening.
Some people have reverted back to analog gauges. Others have upgraded to GPS. One rebuilt the wiring harness with much larger wire & got great gauge stability; even when switching on the blower (or some other high amp device). Probably most of us still fuss with the aggravating digital ones that came with the boat from the factory. Can't recall anyone getting AccuSki to work. Our Administrator
affectionately calls it AccuSuck! Gauges are definitely the Achilles Heel of an otherwise bullet proof boat from ~20 years ago!!
Incidentally last weekend, after we removed the carpeted board between the fuel tank and the trunk (thorough cleaning), put a flashlight on the port or starboard side of the yellow plastic fuel tank, looked toward the light from the stern, and moved the flash light up & down until we saw fuel sloshing around inside the tank (boat undulating in passing rollers). Got a great idea how much fuel was there. Did it several times to verify the fuel level was slowly dropping while we burned gasoline.
The carpeted board isn't too hard to remove with a #2 phillips screwdriver & several screws. Probably not a good long term solution, but might get you by for a while... Or at least give you a better idea when you'll be stranded with a dry tank.
Any who, welcome to the site & hope y'all enjoy the boat!
We'd be out this evening if it was only raining. Somehow can't find many people that'll dodge bolts of lightning!!
