Yeah, that's a little more than I'm willing to tow with my Ex until do my V/b code spring swap.

My obs would run 205-210 cruising at 75mph empty. Twin pumps instantly turned it into 225-230. My gen3 pumps would run 215-220. That's around 80-85* ambient temp.

I don't see it necessary to drill the front cover as many have had twin pumps without issue.
I have run these for a while and I am not having problems, but I remember a few years back reading somewhere, that twin HPOPs increased oil temp significantly.
Using the dieselsite spacer to feed the rear pump and have a secondary resivor feed as well shown in the second pic.
Sorry no up close pic of the secondary feed to the resivor.
Disregard the tty headbolts as it was for mockup before studding.
I'm really wondering what temp thermostat would be best, and what others have seen for oil temps with twin pumps.

Damn, krist, you weren't sh!ting when you said you had some work done on your setup! :toast:
Looks good.
Ok so maybe my readings are not completely out of wack.
What temp thermostat were you running?
I will still use my IR gun tomorrow morning after my 70 mi drive to work to compare oil pan temps vs res temps.
Ill post the results.
Thank you for your input cowboy, just what i needed.

You need to run the return line off the IPR back the crank case. Before I did mine I was seeing upwards of 265 degrees oil temp of normal driving.
There is a recessed spot right on the top of the stock hpop reservoir that you can drill and tap and plumb it in there. It drains down into the crank case.
I think after I did this I was seeing about 210-215ish. But I have not had the dual pumps on for over a year. They have been there since January waiting to be fixed....LOL
I still need to get this POS SRP1 off my truck and sent in...LOL

When I was having my oil temp problems. Everyone was pointing me towards everything else.
We had an IR gun that was saying it wasn't that hot but since the aluminum sheds the heat so quickly it was reading almost normal. But when I took a normal thermometer and opened up the reservoir after driving. I dropped it in and it verified almost exactly what the truck was reading.
The return goes right to the HPOP spacer, draining down back into the case.
Shown in the first picture above.

Then have you stuck a real thermometer into the reservoir and verified the temp. Right after you shut down the truck.
The temp sensors can be +- like 7-10 degrees off. Your 230-235 doesn't seem really that too far off with the 203 thermostat.
I had one of those 203 tstats that I got rid of. It was stuck closed. Went back to a Ford stock thermostat 19X?

No wonder your temps are high , if your pumps are retuning all there hot oil to the hpop res. That's where the oil temp sensor is located also .
I'm sure the oil in the pan is way cooler.
