No. that is the fuel shut off solenoid. The thing it is bolted to is the injector pump. the lift pump looks to be in the bottom left of the photo.

l have before but not this time. l did fined what your saying is the off solenoid . the plug had pulled out but found it trying to start after repluging it in but never did . but l had pulled fuel lines of it at that stage and put back on . l know it had stoped other times after hitting a bump which now may of been a lose wire on the off solenoid

There's diesel all over the place in that photo.Clean it up with a spray can of super-cheap degreaser, then start it and look for the leak, which might be related to the problems you're having.

If you bypassed the lift pump with an electric pump, and it ran, then surely you've narrowed it down to either the lift pump itself, or hoses, fittings, filters to the lift pump back to the tank. sucking a bit of air.

has it got eletric fuel pump or mechanical You should know the 2 big main hoses on your picture are the fuel hoses from and to the tank from what i can tell on your picture. these old pumps normally just shut off when the fuel-delivery rack is retarded to zero. There is 2 arms on your picture . I somwhat doubt that the electric thing is a shut off but cant tell from thet picture . Diesel pump should have a wee bleeder screw to bleed it when it went dry ,Also i hope you got a fuel filter and the filter is not dirty or blocked

l put the pump on where it comes strate out the tank so would of pushed its way through what ever may be blocking it. l mite put a by pass on it to see if l have a blockage in the line

I had a diesel once that had a fault with the primary pump and it seemed to get air in the system every start. The primary pump was on the side of the Injector pump. I bypassed it and fitted an electric pump and it solved my problem.

kubota 3's dont use a lift pump the thing on injection pump is the shut off solenoid needs power to start as above sounds like electric pump is priming it cause its leaking!

that would be connected to a knob to pull when you shut it down on the empty leaver then

now you say that when l was puching the fuel through it was leaking under the machine under presher . so will put a new line around the machine to test it

l bought some new line tobypass the old one to see if that would fix it but did not. maybe the one on the machine spites to 2 diffient areas! any clues! ta

no idea but you cant have fuel leaks air in the line and it wont start no more. Dont understand what you did exactly all you need is fuel to the injector pump with no air.

So at any point of dissconnecting all these fuel lines, have you bothered to bleed the air out of the injectors/injector lines!
plasticboys,

l have and made it run on another fuel pump. now l have found a electric one that does not pump unless you turn the key on and off l guess that is the problem

Have you checked injector lines for leaks! If one is leaking, there will be no pressure to the others.

l have pulled the lines on the petrol pump .it just does not tick. has it a relay in it or not
