question Too run, or not to run ? Zetor 7045

First of all { cool, & very interesting } web site

I have a Question ?

My problem is that my Zetor 7045 4wd shuts down on it's own. I

replaced the fuel tank, and put a clear see through fuel filter in

supply line. I went as far to installed a electric fuel pump to help.

I cleaned primer blub out after finding pcs of inner fuel tank liner

pluging orfis The ZETOR ran for appox a hour afterwhich

stopping, and refused to restart. I started the ZETOR yesterday

w/ no problems and ran it for fifteen min. at varies rpms w/ no

problems, but The Zetor is starving for fuel and I'm not sure

why? what are your thoughts ????

Change the fuel feed pump under the injection pump. I had teh same problem caused by just one little fiber ring.

What's involved in changing a fuel pump ?
Thanks

I think you could try to blow the fuel lines clean with an air compressor first. I think a line is plugged.

Sometimes you can get a vacuum in the fuel tank if the breather is blocked.
Test by removing the filler cap just after it stops - do you hear air rush in?
The pump is more likely the problem as above.

The problem turned out to be a crack in the rubber supply fuel line. the crack allowed the fuel pump to suck air in.
