Plug the outlet on the canister and use an air gun to blow air into the center tube.
This should aid in locating any unplugged holes in the tube or blow clear any plugged holes.

[QUOTE=JSeery;1883898]I would bet the return holes are there, they can be hard to see. There is really no reason they would not be there unless it has been modified for some reason, which would be odd. The restrictor on the inlet side can likewise be somewhat difficult to locate. It could in at the fitting coming out of the block or inside a T-type fitting going into the canister. It can probably be in other locations.

Thanks, I'm sure they are there but they are really plugged and hidden. I have applied 100psi on the tube and no leaks so they have been that way a long time. I'd feel a lot better about drilling a relief hole if I knew I had a restrictor on the inlet. I'll have a look at the supply end near the oil pressure sending unit maybe it is there. Thanks again for the reply

Thanks 51 MERC-CT, I have tried that and 100psi won't break it loose.
Thanks, Dan

Sounds like it's time to remove the canister and the lines and clean them out.
You may have solidified sludge.
