Want this question answered?
you should unhook supply line and return fuel line from back of head this will bleed fuel from head. to bleed entire fuel system unhook fuel lines at fuel tank be sure to plug fuel tank or you'll loose all your fuel in tanks.
The vacuum canister is up above the fuel tank (visible on driver side, forward corner of fuel tank.
Yes, If your pulling a vacuum in the fuel tank, the fuel pump cannot deliver fuel to the engine and will stall. Check the fuel tank vent hose and fitting, a common problem is wax build up in the fuel tank vent screen. If you replace the fitting, remember it is a requirement to have the screen in the fuel tank vent. Quick test is to run the boat until it stalls and remove the fill cap, listen for vacuum release.
As the fuel is being used by the engine this creates a vacuum within the tank. This vacuum will cause the tank to deform and crumple it is not vented properly. Therefore, you have a problem with venting. I would replace the fuel filler cap first and go from there.
the total holding capacity of the fuel tank.
I dont understand. The evap pump is a vacuum that sucks the fuel vapors from the tank so they are not released into the atmosphere so wheres the problem?
it is vacuum,caused by the cars emission system
It is not pressurized. A breather valve at the fuel tank allows fuel vapor to flow out of the tank and be stored in a charcoal canister until it is drawn into the intake of the engine. It also allows fresh air into the tank to prevent a vacuum. The fuel cap is not vented, all air moves through the breather valve. Technically it may, at times, be pressurized or have a vacuum. However, a properly functioning vapor system should limit that to a max of .725psi, or a vacuum of .45in. Hg.
under the hood next to the fuel rail and vacuum hose
If you mean the " E " at the bottom of the fuel gauge that means the fuel tank is ( Empty , that there is no fuel left in the tank )
You first have to disable the fuel pump by pulling out the fuse. Crank the engine over to bleed off the pressure and then disconnect the fuel lines from the tank. After that you drop the tank and the whole assembly will be on top.
Injectors will self bleed when vehicle is "cranking" provided system is working normaly. The pressure regulator will bypass all extra fuel and return to the fuel tank providing constant fuel supply to injector.
