Nope, that's about right considering the rack is in the low idle position. If you move the rack towards the high idle position the “spurts” will get progressively larger. This is the amount of fuel that gets atomized by the injector.

Ok, this is how it works. That upper portion of the fuel injection pump that has the banjo bolts is an open chamber, or cavity, which is flooded with fuel under pressure (~10-20+ psig) created by the back pressure of the Pressure Regulating Valve (PRV) (all diesel engines have some such valve). There must be pressure for the engine to operate efficiently, if at all. It doesn't really matter if the PRV is at the front, side, or rear of the fuel injection pump so long as it is associated WITH the RETURN LINE and NOT the inlet line from the fuel filter. The return line may take a circuitous route through the injector leak-off lines, but ultimately goes back to the tank. I try to keep it simple.

This may not be happening after all. The Laser Grade company won't sell to me because I live too far away. They wouldn't be able to hold my hand, it appears.
I contacted Trimble and was referred to my local Caterpillar dealer. I'm waiting for a quote as we speak. I just know Cat is going to hit this one right out of the park.

It would take me an eternity to match up all of those color code combos…

Ouch! I feel for ya Eric.
Good thing you didn't have fiber-optic service (FiOS), those splicing tools are pricey, and not sold at Home Depot. Try the budget models at $14.5k. So the guys that come out to do repairs and splicing aren't inexpensive either.

Check the nameplate on the pump, if it has a “CBN” number it is the same one used on the tractors, or at least it would be interchangeable. You need about 6-7 GPM and about 2,300 psi. You can also install a Prince PTO pump that slips over the splined shaft and runs in the 540 r/m range – no overdrive (“gearbox”) necessary (it's what I did).
So, what happens when you move the left control? Are you moving it front to back or side to side?
“…so there are the last…”
What does that mean??
Is this your first backhoe? Are you a certified five-position welder?
Curious why you used AW46 hydraulic oil instead of AW32? Are you on the equator?

More than likely the relief valve is dirty and stuck so you dead-headed the pump. My guess is that you didn't flush the system first before you put it into service, so now that will have to be performed – after you clean out the reservoir and relief valve, and repair or replace the pump. Also be sure to have the correct relief valve setting when it's reassembled ~2,200 psig. Sorry.

I can't make out much from the pics. Even tried a little photo-shop. Can't tell where the break is. Possibly-maybe, brazing with fish plate or just fab a new part from steel?
