7711 Fuel leak behind injector pump

SteveS42240 · Aug 31, 2018

A friend has a Zetor 7711 that has a fuel leak behind the fuel injector. It appears to be coming from a hose behind the injector pump. I need some help on how to change that hose. Will the injector pump have to be removed or can the hose be changed with the pump in place?

Thank you.

You say its an "injector" line but mention the pump??

It is a rubber fuel hose, not a metal line. I will take a picture and post it when I can.

I said it is a HOSE behind the pump. It appears to be a flexible rubber fuel hose that is looped behind the pump. I did not have adequate lighting and tools to investigate further. I will take pics and post them with more information in a few days.

Probably the fuel return line back to the tank. Does it connect to a metal line that comes off of all of the injectors? If so you could just add a new line and run it at about the same height and angle of the original hose and just disconnect the old one from the fitting at the injector and leave in there.
