External oil pump -- Converting a conventional wet sump oil pan

The pump I have is Peterson Part #03-3852, 1.100 pressure section, 4 ea. .875 vacuum scavenge rotors. Pump fittings are, Outlet –12, Inlet –16, Scavenge fittings Inlet two –10’s, Outlet –12. I have this same pump on my 598. $850 includes shipping to lower 48.

If you use a motorplate it can be mounted to that using the bear claw mount it comes with. If you don't have a plate, your best option is to call Phillip Oakley. He's a Peterson dealer and can tell you more about what they have for mounts than I can. I'll see if I can find some receipts for the drive and other stuff, off the top of my head I have no idea what I paid for it.

Those mandrel bend pickups are something I had custom made several years ago for external pump conversions. They are 3/4" I.D. [1/16" bigger than the i.d. of a -12 hose] and has a -12 female thread so, one can use a -12/-12 or a -12/-16 adapter fitting. I think I may have one left. If you are interested I'll check on it and try to figure out what I have in it for $s.

Can a wet sump oil pan be converted to properly work with an external oil pump? I've looked at Petersen's website and don't see any mention of conversion parts...

Thanks for the help!!!

Have a good day!

Michael,

Be careful here that you don't get a two stage pump mixed up with a Wet-Vac pump that Peterson makes.

1. A Wet-Vac is a combination single stage oil pump with a built in vacuum pump. It requires a breather tank for the outlet side of the scavenge sections, which generally pull from the valve covers.

2. A single stage belt driven oil pump is just that, and does not require a breather tank. The oil from the pick-up goes to the inlet side of the oil pump, and then the oil from the outlet side (pressure) of the pump goes into the block, generally at the oil filter pad.

3. A two stage, three stage, four stage or five stage pump is a dry sump set-up that requires a dry sump tank, and also a breather tank or at least one built onto or into the dry sump tank.

4. My question is, where are you going to put, or dump the oil that comes from your low mounted turbo, using your scavenge section?

You have just answered a question from......8/10/10.

that would be great Lem, let me know.

To Charlie Evans - Charlie, Im switching my 514 BBF to an external oil pump also. The one I have is a Stock Car Products single stage pump. (a buddy had it rebuilt, but just sitting around in his garage for the last few months...so...free is free...haha) He gave me the pump and the filter adapter, no gears or belt. Because of the extra work his engine builder did on his small block Ford, it was plumbed differantly then i will have to on mine. I plan on using a #12 hose to come from the pan to the pump ( it has #12 fittings on both sides of the pump already) Then from the pump it will go threw a Peterson's 400 oil filter (75 microns) then into the oil filter adapter. My questions to you are:

1) Should I put the oil filter before the pump to help catch filings that might end up in the oil pan ?? (is it better to pull the oil threw the filter or push it threw?)
2) The oil filter adapter has 2 threaded holes, 1 in the middle and the other closer to the side. The oil that comes from the pump, should it go into the centre hole, or the outer hole? The other hole will just be blocked off.
3) What gear ratio should I be looking to run on a 514 BBF (I cross the line at 7000 rpm)(Drag race)

Thanks

Charlie....hahahaha...sorry Buddy...when I asked what gear ratio, I ment what gear ratio for the oil pump and not the rear end.

Thanks
Rick

53%-57% seems to work with most pumps.

Rick,

1. I suggest you get a Peterson Fluid Systems catalog. In the back of the catalog they have plumbing diagrams for dry sumps, single stage belt driven oil pumps, wet-vacs and etc.

2. In regards to your first question about filter location. You always must push the oil through your "real" engine oil filter, so "after your pump" is a must. Those that run an optional additional filter before the pump, known as a "scavenge filter", use a different size micron filter. In country boy lingo, the scavenge filters have bigger screen holes. Peterson clearly desiginates the micron size and the difference in their catalog.

3. The adapter hole that you will plumb into, will be the center hole. That's the one that sends the oil on into the block passages.

4. Lem has already answered your last question, but I believe that Stock Car Products generally always suggests 57% as your drive ratio.

Hope this helps,

Charlie

Just wish to add that we have started to offer our Free-Flow pickup kit. This kit includes the pickup strainer box, the tubing (you bend it to your desired shape) and a pickup tube brace and pump flange (these kits are meant to be used with internal oil pump).

Basically, the Free-Flow pickup kit includes the parts shown in the picture below but without the oil pump or pump drive.



They make up an oil pump pickup that would normally look something like this (or whatever suits your build):



You can also use parts in this kit to fab your external line...in fact I'm using these parts on an external line F700 pan right now. We can sell you just the raw parts you need. We are currently doing a run of three dozen of the Free-Flow kits to keep up with demand.

Call or PM if interested,

Paul
