Replaced the hydraulic pump but can not stop it from leaking where the two delivery pipes attach. I have the workshop manual, but it does not say if I should use some type of spray on gasket. Would anyone have a suggestion? The 3 bolts are torqued down, but still leaking.

There are probably some O-rings that should be between the pipe flange and the pump flange. If you did not replace those they will probably leak.
If you did replace them, they may have gotten damaged during assembly.

Russell is exactly right, there is an O-ring on all the flanges.
If they leak with the O-rings in place, try new one's.
If it still leaks with new O-rings check all the fittings and pumps for cracks.

It's always nice when it's something simple!
You can use a little grease to hold the O-ring in place when you go to put it back together if it doesn't want to stay in the slot.
