You'll have to use what you have to figure out how to package and install cleanly, but the attached files show the path.

13 and 14 could either be plugged, or put your oil pressure sender and oil temp sender there. You can also put your oil temp sender on the remote oil filter, which is what I prefer. Your pressure sender may already be up at the back of the intake, you'll have to look and see.

I will try to help. Look at the first diagram in the link I posted for the proper routing. The lines attached to your oil filter adapter don't look like the original ones, but the black hoses in 2nd picture appear to be the right ones. #1 & #4 connect to the Water hose from the sea water pump and out to the thermostat housing. I think the oil cooler is the type that mounts on the Bell housing on the rear of the motor, but not positive. The second link I posted looks somewhat like your setup, but the standard oil filter adaptor like in the first link would work also. 13 & 14 are normally plugged with just a brass NPT fromany hardware store.

I forgot earlier, but you should have an oil pressure alarm switch too, that could go in one of the holes for 13/14.



You also have two different sets of lines. You need the remote filter mount at the block like you said.

Based on the bends in what you have:

5 - Remote filter
6 - Filter adapter at block - Out of filter adapter

7 - Oil cooler
8 - Remote filter

9 - Oil Cooler
10 - Filter adapter at block - Looks like the IN

3 and 4 are in from sea water pump, out to engine.

sorry to be so late in response, but what I have read is that 13-14 cant be blocked off that oil wont flow through block unless those are looped? I have no experience with these engines.
Also I have read about the two check valves that are on block. One in the oil return and another one in either 13 or 14. What do I do with those? just leave them? change them?
Thanks in advance

13 and 14 are plugged on my 502.

That is a bellhousing mounted oil cooler.

Ill plug them then.. then prime it to see what happens.
Also what do I do about the valve that's under where the filter adapter goes?
The block originally came out of a truck..

Filter adapter for remote filter goes on in place of check valve and original filter mount. There should be a valve in the remote mount. Holes on bottom of block ahead of filter were for the truck oil cooler and should be blocked for marine application. Your cooler is routed inline with filter plumbing.
