fuel gauge

[ssr]

:mad: I too am having the same problem with my fuel guage that other owner's report, i.e., when it shows 3/4 tank, I am almost at empty. I took it to the dealer last year for repair, only to be told that it was working fine. Has a solution for this problem been found?

testing

I have been wrenching on Tiges for almost 10 years and for 8 of those I have been asking the factory the same question as you. What is the fix?

Your fuel gauge does work fine, test it yourself. When the boat is on the trailer level it as close as possible. check the gauge. Now, lift the front as hight as you can, check the gauge. Now, lower the bow as low as it will go, check the gauge. If thier was anything less than Full when level I will bet the gauge read Full when the bow was up and dead empty when the bow was down. Now look at the attitude of the boat while it is in the water, bow up huh? gauge will read full until there is approx. 3 gallons left to get you home.

Whats the fix? Any suggestion would help greatly

Greg,
I read somewhere that someone thought the Faria guages have a fuel flow function built in, that if you purchase the sensor and connect it, the guage automatically recognizes the sensor and enables the menu to access the information.

Have you heard anything on this?

BTW, the fuel flow meter I installed earlier this summer is working like a champ!

[Tige M.D.]

The faria guage we are talking about is the Commander series. As far as I know it does have the capabilty to monitor fuel usage but I think there is a little more to the story than just " plug and play". Let me make some calls and I will let you all know what I find out.

Tip,
We at Tige watersports sold close to 200 Tiges this year. Our service department has been servicing no less than 6 boats a day since April not to mention the 20 or so major bottom strikes (underwater gear and glass repair) So, yes, we have been busy.

O.K.
I just talked to harvey and there is a transdeucer and harness that can be plugged into your excisting gauge. harvey is going to get back with me later with more info on this.

Faria does offer a fuel flow transducer that will work with the gauge. Part number SN0019. Tige is in the process of testing the unit and it may become an option for later models.

This is the best description of the problem I've yet to read. It decribes my problem exactly. I don't think there is a fix for it. I've just learned to deal with it.

Just niticed that my digital readout/depth finder/hrs metter/ec... and my speedometer quit working. The speedo adjust has no effect. Is there a small battery that needs replaced like a watch/ 2001 21v limited

Help??

[Tige M.D.]

no battery in there. probably a bad gauge. check the plugs on the back of the gauge.

Recently purchased 2001 21v Limited. What's the battery replacement tktige' was talking about? Any other known issues I should know about or a place to go to find known issues?

Thanks!

The needle in my guage reall bounces around when we are moving, is that normal, or do I have a loose connection??? Also I have the Faria guage.

[Tige M.D.]

thats an old boat you have there, has the needle always bounced or did it just start? if it just started then yea, i would look for a loose connection, either at the sender or at the gauge. alot of times the ground on the sender will erode away over time. it gets pretty wet on your model boat.

I am having major issues with fuel gauges. My stock gauge is not working at all. It has been replaced four times. I now have a fuel flow meter that the dealer installed that dosen't work either. Does anybody make a fuel flow meter that will work with the PCM motor on a 2005 24V. I need help from you guys, my dealer is incompitent. The mechanic says he new the new fuel flow meter they installed wouldn't work, He went ahead and drilled a hole in my dash and installed it anyway because the service manager said it would make me happy. I'm not. I really am not trying to be that hard to deal with, just get me something that will get me with in 10 percent of how much gas is in my boat. I can stop and sit to read the gauge I'm fine with that. Just something close.

Wingnut:

I don't think you're going to get a working fuel gauge. We can all whine about our fuel gauges on our late model Tige's all we want but that's not going to solve our problem. We all seem to have the same issue. Tige knows about and I would bet they are as frustrated with it as we are.

I purchased through my dealer a Fariah fuel flow meter. Last week was the real test while on vacation at Table Rock. At first the unit was off by close to 5 gallons (It said I needed 33 gallons to fill the tank when it only took 28). But after calibrating the unit as specified in the manual, it's much closer - like within a gallon on 35 gallons used.

What unit did you purchase? and why did your mechanic said it wouldn't work? I've heard of other owners here with the Navman and other brands and they seem to be pretty happy with them.

[Tip]

I'm not sure about the PCM motors but if the PCM has a re-circulating fuel pump then a regular fuel flow meter is not going to work. I've heard they do make fuel flow meters for re-circulating type fuel pumps but I've never actually seen one advertised.

I have the Merc 350 MPI and my Navman is consistently accurate to +/- 1 gallon.

The dealer put in the nav man 2100. It does not work because the unused fuel is returned to the pump. My other fuel guage isn't working at all, it's not just off it reads full all the time. As soon as the key is on it pegs to full and stays there, I went through 38 gallons and it didn't mave off of full. Is the faria gauge compatible with the PCM motor and fuel pump system?

Wingnut:

Our boat has the Tige GM Vortec (Marine Power) 340HP 5.7l V8.

I could not tell you if the unit I have would work on your specific engine. Give the folks at Fariah a call to see if they have something that will work for you. They have a few different gauges.

I found this number at their website:
Fariah Customer Service Department: 1-800-473-2742

This is their website:

The Tige gas gauge in our boat is not much better than your non working gauge. It begins to move off the full position after we have used 17-20 gallons of fuel, and it only moves down to the halfway mark when there's only have 4-5 gallons left in the 38 gallon tank.

Question:
In your case - if the unused fuel is returned to the pump, couldn't the dealer put the navman sensing unit before the pump (between the tank and the pump). It seems to me that by doing this, it then wouldn't register the fuel twice. I'm not a mechanic, but it's a question I'd raise.

[Original Wing Nut]

Andrew at Tige' is checking with PCM and calling Tige MD. I don't know if it is going to work from what he is telling me. I gues there is a fuel pump in the fuel cell or something and the fuel is pumped to the motor and then the excess is returned to the tank. I would think there is a sytem that reads fuel leaving and fuel returning that would give me an accurate reading. I'll let all know what the answer is if it is found. I am also wonderng if when a problem arises Tige' calls the MD, what are we going to do with out that guy? Good luck to the MD, I wish Tige' would do whatever to keep that guy around. You don't find guys like that very easy.

I believe the answer to will this work on this engine or that engine is not a simple yes or no. It can depend on where on the engine the meter is installed. On my '04 MarinePower engine, I installed the NavMan in the fuel line between the gas tank and the factory filter/pump assembly. This engine also has a return line from the fuel rail/injectors to the pump. So by installing it where I did, it only reads the amount of fuel consumed, not circulated. But I did have to install an additional filter since I was measuring unfiltered fuel.

If the PCM doesn't return the fuel to the tank, they could do the same thing on it. I hope that this made sense.

I found that Floscan makes a unit that will work. It is model # 5832-231-2. Their number is 206-524-6625. I have agreed to pay the $200 upcharge because this meter is that much more than the nav man the dealer installed, but I feel the labor should be covered by the dealer because, they installed the one the salesman recommended and thier mechanic said would not work. That should be an internal issue. I will recover the expense one way or the other. We'll see Andrew is calling the dealer to have the owner call me. I'll let you know.

[Tige M.D.]

you said the navman will not work? you must have a pcm, from what i understand the pcm has a return line to the tank. i just found this out yesterday.

[Original Wing Nut]

I do have the PCM motor and it does have a return line. The Floscan has two transducers and reads the difference between them. Sounds like it should work great. I'll see next week.
