Trouble bleeding the fuel system/Lucas CAV DPA!

[Arber]

I recently replaced the fuel filter on my tractor and blew all the fuel lines with compressed air for extra cleaning after that went through the normal procedure bleeding the top of filter after that injection pump bleeder screw then at injectors but for some reason I couldn't get good fluid movement from the first injector in the front of the engine the other two were excellent mind you I did rebuild the pump and injectors before, the tractor did eventually start but by observing the first injector line it was moving fluid but not the same as the other two! Now the tractor is bled and starts fine but I am fairly confident that issue with line 1 is quite common because I saw another post stating just that!
What do you guys think has this Happened to you?

EDIT: I'm talking about Ford 3000 diesel

So you have a Simms pump. You needed to reveal that in the first place. You aren't having a problem with bleeding the pump, you have either leakage on the #1 injector pump barrel or blockage of some type.

Dude are you for real you didn't even bother reading the title?

"Has this happened to you?" Has what happened? Had trouble bleeding a CAV pump on a three cylinder Ford? Yes, a few times. Had one where only one injector line wouldn't produce fuel? Not quite sure about that. They can indeed be hard to bleed if the fuel tank isn't at least half full. That's just the nature of the beast. I attribute much of that to the fact it's a gravity fed system and it has a sort of (*******) fuel return system. I've found that when I get one like that it helps to temporarily install an electric fuel pump as a charge pump. There are two in ports and two out ports on the filter base. Typically there will be one unused in port with a plug in it. If I remove the plug, install a fitting I can slip a hose onto, charge the filter with the electric pump it saves a lot of cranking and battery drain. I close the fuel tap on the tank outlet, drop the pump suction line into the fuel tank, turn on the electric pump and then go through the normal bleeding procedure. Having a few PSI of charge pressure at the injection pump supply makes a big difference. Once it starts and runs it only takes a few minutes to remove all that and put the plug back in. Open the tank valve, a quick bleed at the filter base and it's good to go.

Dude, I did read the title, but I remembered 3000s coming with Simms pumps. SOOOOO.....SORRY DUDE!
Anyway, only thing I can think of is a crack in the head or fitting, but pretty unlikely as the delivery of pressurized fuel is equal to all ports.
That said, that is not a bleed issue.
