This has happened to me TWICE in three months. Fuel tank read a 1/2 tank and 15 minutes later (easy cruising) I'm dead in the woods. Im a little worried that its going to happy a lot more with the new power. What have you other guys done to fix this? I've heard some kryptonites have fiberglass tanks that mold with the steps and others don't....... I was thinking about this gadget but im worried it'll clog the fuel line. Any suggestions?

What kind of sender do you have? Put one of these in and you'll be good to go http://www.livorsi.com/catalog/senders.htm

The tanks are tapered, so from 1/2 to full is a lot more fuel. I have been there. I set my sender by the depth in inches. It got great fuel economy until I got to 1/4 tank then I could really see the gauge move, I got about 5 miles the last 1/4 tank.
So now the tank was empty. I put 10 gal of fuel in and set the sender to empty. Now its much better still goes down faster the last 1/4 tank but at empty I have 10 gal left. definitely slowed the gauge down the last 1/4 though. I think I ended up trimming the float wire and sliding the float up 4 or 5 inches off the bottom. So it still reads full but has the reserve of 10 gal at empty. I have a 89 gal tank.

my tank is 11"deep at the sender, so you would think 5.5 " is 1/2 tank wrong..... it follows the hull contour, the 4.5" deep pad holds about 5 gallons is all. See how I messed up when I set 5.5" as 1/2 tank, like I said the gauge moved really fast the last 1/4 tank which in inches is only about 10 gallons. like I said suck the fuel out thru the pickup install 10 gallons, dip the sender in and keep trimming until its right on empty. That will solve the issue.

Thanks Doc, I may try that. I had this fuel flow gauge component when I had my previous boat with a 300xs. It is a VERY useful tool to have and takes a lot of the guess and check stress away when you're in question. Has anyone ever used this with high horsepower?

I had looked at the floscans, but didnt see any applications that handled that much consumption. the most I saw was 30gph. I would have to imagine that at wide open I am using more like 60-70gph, and probably 25-30 at cruise.

My Kryptonite used to have the same problem, kind of like the old GM cars. It stayed on full for 1/2 the tank and when it started to move, I knew I was around 1/2 and at a !/2 it was time to refill. Also, Make sure you guys check the sender/pickup gasket. Mine deteriorated in 2007, 4 years old and created quite a mess and a scary few minutes! All was good and fixed cheap, thank God!
