Show us a picture of what you have. Does it have a large slim hex nut on the side of it, with two banjo bolts underneath, and is attached to the fuel injection pump with three 6mm studs and nuts in a triangular pattern? Normally they are sold together, but you can also get the hand primer pump separately.
Tommy's parts catalog is here:

That's true. I forgot to mention that.

Can't find a $40 lift pump at either site. No lift pumps at all actually. I did find hand primers at both, all notably more than $40. Found lift pump shafts at Circle G. What am I missing? Cuz if a (new) boxed lift pump component is truly available, I'd like to be able to point others in the right direction in their time of need.
That said, the half million dollar TY395E3 engine (complete) is kinda fun. https://affordabletractorsalesco.com/cart/sub_catalog_gallery.php?cid=1771&catid=106&picid=1911&category=Parts%20Center&sub_category=Engine%20TY395&scid=115

The tank has to be 100% completely free of moisture before you introduce fresh fuel into it. That means it has to be warmed with a heat lamp or baked in an oven, not blown out with compressed air. The bugs will just love any amount of moisture to set up housekeeping again. So if you feel what you have done is adequate, then please accept my apologies, but I have been down this road before, as a Cat field mechanic and as a marine engineer.

Here is Phillip's lift pump/primer assembly (kinda dark pic but all there):
Fuel Line Priming Pump
I see Tommy doesn't have them listed now. May be out of stock.

Phillip's is $80.00. Maybe prices have gone up?

I see we're talking about completely different "lift pumps". Yes, technically the hand primer is a lift pump, albeit manual. I've been talking about the shaft driven lift pump that the manual hand primer is bolted to; the low pressure half of the engine driven fuel delivery system. And you're right, $80 doesn't seem right either. I put one on my '85 Mercedes turbo diesel 16 years ago for ~$15. Even today I can still get one for $26. http://www.carpartsdiscount.com/aut...pump/cohline_hand_primer_pump.html?3593=52927 . Since it's metric, I strongly suspect it would screw right on to my Chinese tractors too.
That said, I see a lot more hardware in the Circle G picture than the actual hand primer itself. Since I've never worked specifically on a TY395 fuel system, perhaps "fuel line priming pump" incorrectly describes that particular $80 item. Is there a chance that's the actual lift pump component - WITH hand primer attached?

well im going to for sure try a lift/primer first and see if that does it, and i know you all might think im an idiot for doing so but when i cleaned the injectors yesterday i did take them apart and flush them out, it ran better afterwards and then i began to adjust them to see how it would run the tighter they were the worse it ran when i loosened them up it runs fine until i put a load on it there for i know it is definately not making enough pressure to open the injectors as i said it runs better when i pump the primer so that shows me that it is bleeding off and with the fuel leaking past the shaft i believe it is loseing it at the primer so i am going to try it first before i spend $700 as i said thanks for everything and dont worry about offending me i have thick skin you are just trying to help and i appreciate it.

I use a 12 to 14 psi electric fuel pump its an inline cheap (70$). It might cause a few leaks or drip but it will keep fuel flowing.
I would probably forget the manual supply or lift pump. Do check the oil supply in the governor if you have one. and the oil supply in the injector pump.
Check you injector distributor pump take the injectors out then put them back on the fuel lines spin the motor let em spray. Not a opening pressure check but you will be able to see if they work and if the pattern is fine or coarse. A good fuel supply throttle open should give a fine mist.
Carbonized injectors are probably OK soak em in brake fluid clean em and use.
It just sound like a leak at: connections, hose, filter, filter bowl, or copper washer.
Find the real problem before you throw money at it
