Can anyone tell me exactly what path the oil takes from the pump to the oil pressure sending unit? I get no oil up to the sending unit, even with a new pump and I'm trying to trouble shoot the problem.

THanks

Did ya prime the pump and filter? The oil comes from the pump to the filter then to the back 3 way split to the lifter galleys and main oiling. If yo can't get oil to the sender don't know. If ya are trying to prime it it turns counter clockwise with the drill,best I remember (or was that way for a Ford??)

 

and how are you spinning the oil pump? with a drill and a primer, or...?

 

spinning it with a drill and a modified primer since I couldn't get a real one under the cowl

I'm pretty sure it turns clockwise, at least that is how I was able to get oil out of the pump by dipping it in a bucket of oil.

All the gallies are clear. I've checked and rechecked them. Even put on an old oil pump out of my stock LT1 (with the same pickup since the stock one doesn't work in a Canton pan). and still no oil/oil pressure to the sending unit.

 

can you feel/hear the drill lugging when it is pumping oil? Does your modified primer have the bushing around the shaft that goes down in the hole(needs it)?

 

If ya are just using a shaft with no sleeve to go in the block to transfer the oil then there is a big opening in the cam gear area that will not let it build pressure. Look at your pump drive and ya will see. A primer has the piece like the bottom of your drive to build pressure.
