Ok Jason thanks mate, I'm going to plumb the hand pump into the tender water tank, down the side of the boiler to the left hand clack valve, then on the other side plumb in the injector, once I find the correct one.

As for the steam manifold the steam to the lifter I will blank off and only leave the right hand of the manifold fitted with a pipe and globe valve to the injector.

On the holes not used on the water tank I will blank these off also.

Does all that sound correct? Hoping I'm starting to understand it before you get fed up with me and tell me to go away

Personally I would go for handpump and mechanical pump but your hand & injector will be OK

I think what puts me off the mechanical pump is the fact I'm missing so many parts already that finding the pump etc is an extra item to the list, I would need to find the eccentric and machine the pump.

Sounds like I'm being lazy but I'm just trying to keep the engine simple until I fully understand them, I thought if I at least get the poor thing running after years of no life I could then add parts later on.

So may I just ask when you turn the steam on into the injector that forces water into the boiler via the check valve? I searched injectors and notice the seem to have numbers like no 4 injector, how do I know which my model should have? I owe you a drink for your patience and help.

Yes when the globe valve is opened the flow of steam draws water from the tender and it enters the boiler via the clack (check) valve

As its a small 2" tractor a No 3 (14oz) would probably do the job

Great, thanks very much.

Without yours and others help on this forum I'd never understand, being only 37 this is my first engine and I hope to build on this one.

Thanks

I've found a number 2 injector, which provides 11oz of water.

This takes 5/32 pipes which is what the rest if my fittings are, my engine is 2 inch scale but only 24 inches long which to me is more 1 1/2 inch with some other engine's.

Saying that will it be safe to fit a number 2 injector? I could buy a number 3 but would need to but all new fittings?

Should do you and as you say easier to plumb in as the pipe sizes are right.

Cool thanks, just one last question and I will just get on with it and leave you be.

Do any pipes need to go to the water tank to add pressure? The injector would draw water by itself from the tender tank?
