Easy way to install fuel line and primer bulb return line into gas tank

Chainsaw fuel lines enter the gas tank from holes in top of tank. They are sized for a tight fit to prevent leakage. Make it easy on yourself when pushing the line through the tank by cutting a long lengthwise taper cut with razor knife 3 inches or longer to easily feed through that tight hole. Once started you will then have to grab it through the gas cap hole with needle nose pliers, then cut the tapered end flush and add fuel filter. Readjust inside length by pulling from above, then cut to length to upper carb fitting. If connecting to primer bulb a filter is not required and make sure the line goes to fitting on primer bulb marked tank.

Out of Diesel

This particular JD engine has an individual fuel pump for each cylinder. The injectors, fuel lines, and pumps are not accessible from outside of the engine. There is a hand primer pump built into the top of the fuel filter. Start by removing the rubber outlet line from the filter base and pump the primer pump until fuel come out of the filter base outlet. Ounce fuel comes out of filter reconnect the line and continue pumping by hand until the pump button feels solid, then crank engine until it starts. This works better if a helper is available to operate the starter while continuing to pump the hand primer. This is normally all that is needed after running out of fuel.

If fuel does not come out of fuel filter base there may foreign material inside of primer pump. Primer pump can be disassembled and cleaned. If fuel comes out of filter, primer pump become feels solid but engine does not start the fuel control rack inside of engine may be sticking in the off position. This may sometimes be overcome by clicking the key switch from off to on rapidly. If not you may have to have your dealer remove the governor cover to free the rack.

Tractor is not getting fuel pass the fuel fi; filter

Check the fuel lines,fuel pre-filter[screener] and check valve,all of these are ahead of the fuel filter.Also if the fuel filter is not the problem then the primer pump on top of the filter housing may have a leak or debris in the diaphragm so that you can not get the fuel to completely fill the filter.Once the filter is full,full fuel out of the bleed screw on the filter housing,then you need to turn on the key and keep on pumping the hand primer.If it still will not start then get a 11/16 wrench and crack two lines on the injection pump.Crank over the tractor until it sounds like it may go,tighten the lines,the crank again and it should start.

My 5310 will turn over when starting but will not start. I have replace air filter, so why won't it run?

The fuel filter may be plugged.Try bleeding the fuel system,open the bleeder on top of the filter housing and then pump the hand primer[above the bleeder].If you can't get fuel then you may need a strainer or a check valve,located in the fuel line before the fuel filter.If fuel is not the problem the you need to check and see if there is power to the fuel solenoid in the injection pump while the tractor is cranking,is so replace the fuel shut off solenoid,if not,replace the neutral bypass relay in the fuse panel.

I have a John Deere 2020 diesel. I can't get the fuel pump off

You need to remove the nut under the cover in front of the pump and then borrow a tool from a j.d dealership to pull the coupler off the pump,you may need the dealer to do this because they have a no lend pollicy for their special tools.Hope this helps.
