Fuel guage

[Tip]

Chris,
I put the flow sensor on the rear port side of the engine. The rubber fuel line enters a metal block that's hooked to some kind of filter. I cut the rubber fuel line about 3" below where the rubber fuel line hooks to the metal block/filter. The instructions for the fuel flow meter recommended installing the fuel flow sensor in a vertical position to minimize the effect of bubbles. This was the only place I could find where the fuel line was vertical.

Hope this helps.

"Hello. My name is Tommy and I don't know how much fuel I have in my boat."

This is so frustrating shopping for a $200 fuel flow meter to compensate for the inop gage on my $40K boat. My 04 22V has read "Full" through three tanks of fuel. Has anyone had a satisfactory answer or fix from their dealer or the factory?

Thanks everyone for the fuel meter info. I'm sold and I'll let you know how mine goes too.

Hello to all who have a fuel gauge problem knowing how much gas is still in the tank. I have installed the Navman 2100 Fuel Flow meter on my 2004 22i. Out of the box with no calibration it was within 4/10 of a gallon accurate. There is a way to calibrate it and it should be even more accurate. It has proven to be a very good investment and addition to the best boat I have ever owned.

FUEL GUAGE

HOOTS,

IT IS PROBABLY JUST THE SENDER. MINE WORKED TO ABOUT HALF A TANK AND THEN WENT TO E. THE FACTORY SENT ME A NEW ONE THAT WAS THE SAME STYLE WITH THE SAME RESULT A COUPLE OF TIMES, BUT THE THIRD ONE WAS A TOTALLY NEW STYLE AND IT HAS WORKED VERY WELL. MY FRIEND HAS AN '04 22I THAT HAS THE SAME PROBLEM. IF HE GETS IT FIXED I WILL LET YOU KNOW THE RESULT, BUT I THINK HE IS JUST GOING TO SELL IT. IT SHOULDN'T BE NECESSARY TO BUY A FLOW METER. THE GUAGE WILL WORK.

cool fuel

Thanks Tip for the quick response.

I've been all over my motor trying to find the best place to install this fuel flow transducer. And as luck would have it I have another question for the experts out there. Can I cut the fuel line that runs from the Mercruiser Cool Fuel system to the fuel rail? I have pictures available that I can upload if anyone needs to see what I'm talking about. If this works I have a great place to install in the vertical position. My engine is a 2000 Mercruiser MPI. The cool fuel system is located on the starboard side of the engine just behind and below the alternator with an insulated fuel line running up to the fuel rail.

Any help is greatly appreciated!


Thanks,

Chris

Transducer location

I put mine about 2 inches below the water seporation filter. I put a small metal in line fuel filter about 2 inches in fornt of that. I had to use a zip tie to hold it out of the way so the engine cover would not catch on it when I close it.

FUEL GUAGE

I can't believe all of you just accept that your fuel guage doesn't work. You shouldn't even have to consider a flow meter as an option. The sender can be fixed and the guage is very accurate.

good luck

Jason, The factory has sent me 4 diffrent senders. The dealer put in 2 of them and to speed things up I put in two of them. I am sick of tearing my floor out to replace them. The tank is so shallow the float has very littel room to move and even moving it with your hand outside of the tank you see 1/4 tank diffrence with 1 inch of movement. Other than this I love my boat.

fuel filter

what kind of filter did you guys use? I've tried to find one that meets the 30 micron filtration specs from Faria. But I can't seem to get any help from my local parts shop. Just curious what you used.


Thanks,

Chris

Auto Zone

I just used one of those metal inline filters from Auto Zone, The kind we used on old" 1970's" cars. Just ask for one to fit a 3/8 inch fuel line. They cost about $3.00. Make sure it is metal, they also make some see through plastic ones. You will need 2 small hose clamps.

good luck

Moved,

The last sender I installed was not like the others before. This one has been in the boat now for a year and is as acurate as any auto. Trust me, I have tested it to the point of drifting into the gas pumps at the marina. I will post a part # for the sender this weekend.
Also, I love my boat as well, but she is tougher to maintain than the girls that are in it on the weekends.

Sender Part Number?

Hi Jason,

Any news on the part number for the sender that does work? I'm eager to fix my fuel gauge problem, but I don't want to go through getting another sender that does not work (I know you've been through that already...)

Regards,

Rolando.

Sorry for the delay. The sender that works does'nt have a part # on the top. However, it looks completely different. The exposed part of the sender is about 1/2" thick charcoal color plastic with positive and negative post exposed and marked. Also shows 240/33 ohms at connections. Since installing this sender my guage has been perfect....other than I wish it would slow down now that gas is $2.25 on the water.

Part #s that DO NOT work are. FMT 1095-5.5 0138 and FMT 1095-5 0131
each of these are just thin steel top with solid wired positive and a ground post. I'm sure the 5.5 and 5 in the different part #'s above refer to the different lengths of the senders. That is the only difference between these two and neither worked.
Check on your gas tank next to the sender and you will find the tank Mfg. #s and this will help the guys at Tige get you the correct sender.

[Tige M.D.]

the sending unit you are talking about is called a centroid sender. it does work better but it is still not 100% accurate.

[Tige M.D.]

Faria is shipping me a fuel flow transdeucer for the commander gauge. I am going to install it in a new boat and test it.

For all of you that have this problem, please be patient. I don't want to claim to have a fix for this and it turn out to be a bigger problem. I am going to test this around the middle of Sept for 10 days and will let you know the results.
