Why is fuel not getting to the carburetor?

No fuel at your carburetor can be caused by many things. It could be a simple issue like a fuel filter plugged so tight that no fuel can pass through. Another logical cause could be the fuel pump. A hole in the fuel line on the tank side could also cause the fuel pump to suck air instead of fuel from the fuel tank.

Why is there no fuel going to the fuel tank?

Another logical cause could be the fuel pump. If the fuel pump is electric, the 12-volt power may be shorted. A hole in the fuel line on the tank side could also cause the fuel pump to suck air instead of fuel from the fuel tank.

Why do I have problems with my fuel line?

Ethanol gas causes more fuel line problems but using ethanol-free gas is not a guarantee you won’t have problems. New hoses have an impermeable liner to keep ethanol from degrading the other hose material. That liner can delaminate from the outer hose and cause blockages.

What causes a fuel line to crack on a boat?

On any line older than 5 years, the sun causes the bulb, rubber end connector inserts, and fuel line to age, shrink, harden and crack, leading to tiny air leaks that prevent the fuel pump from pulling gas into the motor, especially at idle.

How do you check the pressure of a fuel pump?

If equipped with a mechanical fuel pump, remove the fuel line to the carburetor and connect a fuel gauge to the fuel pump. This should yield a low pressure, under 20-psi when the engine is cranked over. Check the mechanical fuel pump by placing a fuel line into a gas can and attach the other end to the intake of the fuel pump.

What happens when your outboard fuel line is blocked?

A blocked outboard fuel line prevents fuel from getting to the motor. It generally starts with a partial blockage, where playing around with the fuel hose and pumping the primer bulb will get the motor to start or keep it running. But blockages don’t cure themselves.

What are the problems with fuel line hoses?

The hoses with the grey outside coating (UV protection) seem to have more problems than others. Attwood brand hoses seem to have more problems than some others. They had at least one recall of hoses due to delamination of the inner liner causing blockages. OEM hoses seem to last longer before showing problems.

How old is the outboard fuel line hose?

In talking with clerks at the local NAPA store, West Marine, other cruisers and outboard mechanics, it seems that we are not alone in our outboard fuel line problems. For the record, this hose was made by Attwood and is not quite 18 months old.

Are there any problems with Attwood fuel line hoses?
