190xt dying

Ive got a 1969 190xt. It takes a couple minutes of cranking to get it atarted, everytime you start it. Now it will run for a bit, then just suddenly die. Sometimes it will only run for a few minutes, other times a half hour or so. It stutters for about 2 seconds then off. Seems to me to be losing prime in the fuel system. Ive tightened every fitting on it. Bte it also has an aftermarket electric fuel pump right before the fuel filter. Thank you in advance.

That electric fuel pump trick was prolly a farmer cure for what's really wrong with it, lift pump, in the injector pump, is losing the carbon vanes, and clogging the works up, would be my guess...

Check your fuel source from tank, Ive had a 190 clog up at both sediment bowls on each side of tank and cause it to do similar thing.

Loosen timing window to where fuel leaks out then try it. If it runs ok then, weight retainer has come apart, pluging return fitting.    MACK

My 190 does the same thing,--- but I think it might be two things causing the problem,--- 1 is crap in the fuel tank and 2 the governor surges BAD unless you pull the tractor HARD, then it runs smooth,--- ( until tank clogs!---might be 5 mins. or an hour!)---cant get the tank off to clean it without getting rid of the cab and fenders, from what I can find out.
Its a good tractor, but not a trustworthy one!
As far as primer pump, Khuns ( ac dealer) wanted $ 185. for a new one, so I went down the street 2 blocks to napa and got an electric pump for $ 50. and put it in place of the hand primer pump that was leaking BAD.---fuel is supplied to transfer pump under pressure and it runs good until tank plugs again.

May not be acceptable fix to CORRECT POLICE, but its MY tractor and I have to do the lesser cost of fix to get things going! thanks; ac fleet
 

 Out to turn fuel on ---IN to turn fuel off. thanks; ac fleet

Ok guys im getting good fuel to the injector pump. But still dying at different lengths on time. Im lost

Loosen the actual injector itself? It will idle forever and not die. But when you're driving it will randomly die, then take a couple minutes of cranking to get it back started.

the return line is plugged up with broken flex ring material, it will look like coffee grounds. Leave the timing window loose on the side of pump, and see if it continues to run without losing power and dying off. Put a bucket under it. This is a very common issue.

The pump has to come off and sent to a pump station. They will clean out by replacing what is plugged and replace what is coming apart in pump.    MACK

The injector pump has to come off and sent in?

Does this pump have a certain way it has to be taken off? Like a timing mark or anything?

A 190XT timing will vary by pump model number, but most are either 24* or 26*. Line the marks in the pump up(small rectangular cover next to name tag with 2 slotted screws holding it). One of the marks will be there already, the front piece will rotate with the engine, and turn the engine until that mark lines up with the stationary mark. Your pump rebuilder will be able to give you the timing spec for your particular pump. You can also scribe a line on the pump mounting flange, and engine.
