Some questions, is the breather free?, could you have water in the tank causing the filter to swell and partially block? Running the motor in the marina is not the same as when under way, the fuel demabd is much higher under load. Also you could put a cleat section of fuel ine betwen the carb and pump and see if it is sucking in air bubbles.

How many gallons does the gas tank hold on a 1997 scout 162 boat

Hi James:
I tried to track this down without success.
If it were me and I really needed to know I would fill a spare outboard tank and put it in the boat and then go and play until the boat coughed and ran out of fuel.
-I'd then connect the engine to the spare tank and continue to play or go home depending on how far away I was.
- Once at a fueling station, I'd fill the tank, and record the amount of fuel needed.
- It can also be a good idea to check the actual amount of fuel consumed (determined by how many gallons to fill the tank) against hours running at different speeds, and also the gas gauge indication when on the step and at idle.
- My personal rule????? never trust the gas gauge, and always start with a full tank.

A 2014 tw 200 starts right up but won't take gas to ride until it warms up for at least 15 min.

I gather its a dual fuel bike? ( Petrol and gas) On cars that are dual fuel, the engine will always start on petrol and switch to gas after its warmed up. If the engine is warm, it will start on gas. I assume bikes are the same. However, LPG can freeze when it is injected through the fuel system. On cars, a preheating arrangement is installed, usually by having the gas pass through a coil or tank that is heated by the engine coolant. As bikes don't often have coolant, I would imagine that a sensor prevents the gas flow until the bike engine is warm enough to stop the gas from freezing when being injected..

Just got my 2000 VW New Beetle with 3/4 tank of gas. Drove it 36 miles and its below 1/2 tank. Could it be the gas that they put in? Or something wrong with the car itself?

On just about every vehicle I have ever seen, the fuel gauge will move faster from 1/2 to 1/4 (I never let a tank run past 1/4. Bad for the fuel pump) than from full to 3/4 or 3/4 to 1/2.
Do a mileage check. Fill the tank until the pump stops, reset your trip or note your odometer miles. Dive a few days or a number of miles. Fill the tank again until the pump stops and not the amont it took to fill. Note the number of miles you put on and do the math.

Starboard needle keeps erratic behavior, engine does not lose rpm nothing seems abnormal, usual see this when gas has water but port engine runs fine from same tank and needle steady

My thought is this may be electrical in nature. I would test with an external guage. If your engines have points, make certain they are in good condition. I suggest considering upgrading ignition to electronic, but that has nothing to do with this event, necessarily. Points are just always out, slightly.

Another test, before anything, may be to reverse the inputs on the Floscan and see if the problem moves or stays. If the problem moves, the starboard ignition is suspect. If the problem does not move, the Floscan may need repair. Make sure that you have tight and clean connections and good grounds.

Put unleaded in a diesel car

as long as you didnt put in more than 30% of the tank capacity,just fill to the top with diesel.then fill again when 1/2 empty.
you will have a hot start problem so try to let the engine cool before restarting and do not use it for stop/start trips until empty.also DO NOT use full throttle or climb steep hills in too high a gear.
just to clarify.....the us/canadian army use gas in the diesel tanks in arctic conditions to stop the fuel from freezing......there engines cost 1/2 $million ......

Got some gas at Kroger,engin off;; had driven less than 5 miles made one stop,engin off;; a mile later loss power,check engin lite on, it started after a minute;; two miles on did it again;; got to store...

Remove the fuel filter and empty it into a glass jar...If you see any water at the bottom, likely there is far more in the tank (there is at least a gallon or more below the fuel pickup) If there's water in there tank needs to be drained and cleaned.

Pegasus 150 looses power then overheats

Check for a fuel filter inline between the gas tank and the carb. Replace that filter ! Also dump half a bottle of Techroline (Chevron) into the gas tank. You are starving the engine of fuel which will lose you power and can cause overheating...check your oil and change often..Techroline can also be found at your local auto parts store....good Luck to you...Tim
