5211 fuel pump mia

[blazer]

bought an old tractor that is missing the fuel lift and primer pump, it has an electric pump fitted and does work for starting the tractor, should i put it back to oem, the manual doesn't indicate how the fuel lines should be connected, anyone know how the lines should be connected ?

The hand primer goes onto the hole on the right, a pipe coming from the tank goes on the bottom hole on the left and a pipe going to the left side of the filter goes on the top hole on the left side.

That's the same as I said only in Polish or something?

thanks, should be able to get it corrected from that, wonder why it was removed.

 

[diyfarmer]

The hand pump is well known to leak and draw air through the tap.

does that include the latest version also ? if so may try to find a good elect pump that could be more dependable.

anyone know the fuel pressure of the mechanical fuel pump ?

A replacement electric pump needs to push a minimum of 10 psi.

Where does the pipe from the tank go to on your picture?

the fuel feed line is the one with the loop @ where the original fuel primer was, is the fuel injection pump a bosch unit, also what is the model # ?

i have read the primers are known to be a problem with leakage so i intend to remove the lift pump and fabricate a block off plate, then move my feed line directly to the banjo fitting behind the pump, thoughts ?

I never saw this been done, we only used to keep things original.

the hose and routing was temporary, was waiting on fuel filters to arrive, the filters are now installed and the hoses corrected, trying to keep as original as possible but use an electric fuel pump.

All the new manual diesel pumps are now made of out plastic so the part that threaded in and leaked is now obsolete.
