Replace fuel injectors in Ford 3930

It all “looks easy”.. all u can do is try.. sometimes the inj body gets rusted in the bore and it takes days of spraying them down with penetrating oil.. so all u can do is TRY..

Have a look at the mounting ear on the inj PUMP..
There’s a timing line on it..
That line corespondents with degree marks stamped into the block..
The line should be lined up or REAL CLOSE to “0*”..
If it isn’t, try moving the pump..

Well, here were are 1 year later and the tractor still has the same symptoms.
We replaced the fuel and fuel filter, bled the lines and ran fuel injector cleaner for several days.

I can get the rpm's up to about 2,000. However, when the tractor is under load from the mower, they drop to about 1,600 and go as low as 1,000.
Now we are debating whether the fuel pump is losing the will to live.

Are there devices that can measure the fuel pressure and/or quantity?
Are there electric fuel pumps that would allow me to by-pass this issue?

Thanks.

Have u checked the filter in the fuel tank..?? Its made onto the shut off tap under the tank..
If the answer is no, try to “back-blow” the filter..
Shut off the fuel, take the line off, stick your air nozzle in the hole and after turning on the tap, blow air into the tap.. THAT SHOULD clear the mesh filter..
Hook it all back up, bleed the air and try it..
