Fuel guage

[macminn]

I have a 19'Crestliner with a 150 horse Johnson. The motor was rebuilt and since then the fuel guage doesn't work. I'm not an electrician, but I assume it should be an easy fix.

Re: Fuel guage

I assume your talking outboard not that motor should have anything to do with it. First is it reading full or empty???<br />My guage stick on empty and when low on fuel must tape guage quite hard, when near full jumps right up on it own. I guess I would start by making sure the the tank is at least half full. Next I would pull floor inspection plate and read the mechcanical guage. If it reads wrong also I think I would work on it first. My 1980 Creastliner the electrical sending unit is mounted on the mechcanical guage. Make sure the wire is tight on the tank and the back of the guage. Tap the guage and make sure it is not just stuck like mine. After that determine if it is the guage or sending unit or wire by grounding the wire at the tank then removing the wire at tank should swing from empty to full it not probably the guage, wire to tank, or power to guage. Good Luck

Re: Fuel guage

Thanks for the reply. The guage is reading empty. I don't know how big of a tank there is but I put 3 - 5 gallon containers in (15 gallons) and it didn't move at all.<br /><br />I'm not that familiar with the boat yet. I wasn't aware of the guage on the tank. Can you give me a better idea of where I can find that.

Re: Fuel guage

macmin,<br /><br />First of all, determine where your tank is. Follow the fill or engine hose as far as you can. If it is the floor, there should be some deck plates over it. Typically there are three.<br /><br />1. Fuel fill hose access.<br />2. Fuel to engine access.<br />3. Fuel guage access.<br /><br />If the tank is mounted in the rear near the transom, you should still have a guage (mechanical) on it. Follow the fuel fill again to locate the tank.<br /><br />Since you had engine work done and you equate this to the fuel guge maladies, I would be thinking someone left a wire off, particularly under the dash.

Re: Fuel guage

djohns19....I agree that this is mostly likely a broken or loose connection but I'm doubtful there will be a mechanical guage. Macminn when you find the tank access you should have the fill hose, the engine line, a vent hose and the fuel sending unit. Try going this website for some troubleshooting info.....good luck!

Boatin Bob,<br /><br />What I was referring to was the sending unit. Most of the ones I have owned, there was a mechanical fuel readout dial on the sending unit.<br /><br />Good tip to send him to Teleflex.

Re: Fuel guage

djohns19.....that's interesting. In all the built in tanks I've had there has only been the sending unit which is just a round plate with 5 screws and gnd wire and S wire. Inside there is the usual float which just goes up and down and changes the resistance (usually 33 to 240 ohms) which drives the guage. It would be very helpful to have a mechanical as well to verify operation of the electric one. That's the first I've heard of possibly having both
