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.
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.
What does it mean when your fuel pump is not working?
CASE 2: Fuel pressure IS NOT present. This usually means that the pump has failed, but not always. Before condemning the fuel pump as bad, you need to make sure that the fuel pump inertia switch has not tripped and therefore blocking power from reaching the fuel pump.
Why is ethanol bad for the fuel line?
Ethanol is a problem for a lot of reasons, not the least of which is fuel line decomposition, including delamination. Some of those little pieces can end up clogging jets leading to carb rebuilds. Phase separation leaves globs of ethanol in the fuel that the engine cannot run on.
Why is there no pressure on the fuel rail?
If the pressure at the exit side of the fuel filter is normal and yet the pressure on the fuel rail is essentially zero, it’s possible the fuel pressure regulator has failed wide open, essentially preventing sufficient pressure from building.
What are the symptoms of a bad fuel rail sensor?
Symptoms of a Bad or Failing Fuel Rail Sensor 1 Hard starting. 2 Decrease in power, acceleration and fuel efficiency. 3 Check Engine Light comes on.
Why does my car not start at the rail?
I have no fuel preserver at the rail but got great fuel pressure at the fuel filter . This all started while I was driving and when I went to take off from the stop light the car just shut off and won’t start up it cranks but won’t fire up .
What happens if your fuel pump is failing?
The fuel pump feeds fuel to the engine at a reliable rate; without this pump, your fuel would just sit in your tank, useless and inert. If you’re attentive, you can catch the symptoms of a failing fuel pump and have it repaired or replaced before it leaves you stranded on the side of the road.
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.
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 much does a fuel line spool cost?
About the “automotive” fuel line (hose). I forgot: Thermoid hose is (relatively) cheap @ $17.00 for 25 feet (with free shipping). You can cut a lot of hoses out of a 25′ spool, and don’t have to waste hose since you can cut the length you need for each application. Auto-parts or “small engine”…
