Is the gas tank vent open?

Is the gas tank vent open?
Or you have an obstruction in your fuel line before the primer bulb.
Good Luck!

"Are you running a portable ta

"Are you running a portable tank or have you got an inbuilt tank??

Could be faulty primer bulb, blocked or closed vent to tank, debris floating around inside of fuel tank, kinked fuel line or collapsing fuel line"
 
"put fuel in before going out

"put fuel in before going out & could feel air coming out vent put 35 gallons in holds 70 inbord tank.took fuel cap loose when occured,did not change,primer bulb was still sucked in."
 
"Fuel Anti Siphon Valve)

"Fuel Anti Siphon Valve)
(J. Reeves)

Many of the later OMC V/6 engines incorporate a fuel restriction warning via a vacuum device attached to the powerhead. If the engine overheats, or if you have a fuel restriction, the warning is the same.... a steady constant beep.

NOTE... Only the V/6 & V/8 engines have the above "Fuel Restriction Warning". The warning horn will not sound on the other models.

The fact that a engine is not overheating, but the warning horn sounds off with a constant steady beep, and that the rpms drop drastically would indicate that the engine is starving for fuel due to a fuel restriction. Check the built in fuel tank where the rubber fuel line attaches to the tank fitting. That fitting is in all probability a "Anti Siphon" valve which is notorious for sticking in a semi closed position. It will be aluminum, about 2" long, and the insides of it will consist of a spring, a ball, and a ball seat. If this valve exists, remove it, knock out those inner components which will convert it to a straight through fitting, then re-install it. Hopefully that cures the problem.

The above procedure will cure a restriction problem with the anti siphon valve as stated. BUT, it may also allow fuel to drain backwards to the fuel tank when the engine is not running (siphoning backwards) due to the fact that the carburetors/fuel pump etc are higher than the fuel tank. This condition is not an absolute as the valves in the fuel primer bulb usually prevent this backwards siphoning problem. However.... if this does take place, the cure would be to install a new anti siphon valve.

Thousands of parts in my remaining stock. Not able to list them all. Let me know what you need and I'll look it up for you. Visit my eBay store at:

"found feed line on tank and r

"found feed line on tank and removed barb fitting.nothing inside of it,see through fitting.line goes from there to big spin on fuel filter then to primer bulb & then on to boat electric pump filter and into pump.

thinking i need to replace the spin on filter again & the primer bulb will use shop air and disconnect vent line and blow through fuel lines & vent hose am i on right track??? thanks for all your help rob"
 
"The ethanol shouldn't be

"The ethanol shouldn't be a problem unless the inboard tank is an older fiberglass one... If it is, then it certainly could be..."
 
"If you have an electric fuel

"If you have an electric fuel pump do you
need the primer bulb?
Could it be that the fuel pump collapsed the bulb, and pluged fuel supply?
Just some thoughts.
Good luck
Steve"
