Rich, I have very little room for the lines, so running with one is my preferred option.

Looking at the #21230, with the pump it looks like there are 3 pump inlet possibilities ...and if you count the front one on the block 4..!!?

Does this mean you can use ANY one inlet and just plug the others off?

(just being sure)

In theory, yes. But you should look at the pump's impeller and use the inlet that obviously has the least restriction. This is usually the inlet that comes in from the side of the cover just like Andy's.

you have 3 possibilities,, you CANNOT use the one in the block,,, in using that one oil has to flow through the pump,, like a stock pump does, the pump has a hole on the mounting surface to the block to pass the oil through, the milodon pump does NOT have that ability..

i run a single line to 9500rpm,,, i use a -16line though but many i know have used 12 lines to 9500

thanks everyone. I'll get the #21230.
...& plug the block inlet, then decide on mock up which inlet to use based on space.

I suggested to Steve at Milodon that he make a version of his oil pump for the World block. They could make a pump body that works with their gear set but doesn't have the external inlet. That kind of pump would still have the same volume as their existing pump but would be 3/4 of an inch shorter for more clearance and would be a dual inlet pump when used with their cover and the World block.

Sounds like a good idea, be great if they implement it. I still reckon your cover would clear my engine mount if I use only one inlet (which is all I need).
In any event I bought the Milodon cover today.

I bought the pump a while ago... hope they're a good pump (!.?)

.. AND .... ta da.. the pump cover doesn't fit!

Does anyone make an oil pump cover:

1. external pick up, and
2. remote filer

that will clear the engine mount.? Help please

Help greatly appreciated.

I still think you will be ok with the milodon pump and a stock pump cover like I use, for the remote filter use this on the stock pump cover.

Indy and World blocks usually have a port on the block that can be used for an external pickup and use a stock pump.Most all other external pickup covers require modification of the engine mount.

It is possible to do but you need to modify your motor mount. I can share you some pics.

This is the cover I use. It has #12 AN fittings machined into the cover with a straight shot to the external oil lines.








What's the reason this one would not work ? It looks like the cover you purchased sticks rearward too far , this one does not look as bad ?

Re: I always run two lines

If the rotor cavity is segmented for 2 inlets (like a multi-stage dry sump), you've fine - but you have to run both or you're down 50% on volume.
If it's a common chamber to the rotor, you cannot run 2 lines unless you know that neither pickup will be exposed.
Why?
Because if only one pickup is submerged, the rotor has a choice to draw from either:
1. the thick, gooey, viscous oil from the wet pickup, or
2. the nice clean air from the exposed pick-up.

Guess what happens?

Looks like you need the pump that I was suggesting that Milodon should build. You already have an inlet in the block so you don't need a pump with the inlet on it. That would shorten the assembly by 3/4 of an inch which would probably allow things to fit together.

It isn't a tough project to do, just takes money. The other option (which would be much easier) would be to switch over to a factory Hemi oil pump body.

That cover is one that I custom designed for my car. It wouldn't work for his application because I think he wants an external inlet on the cover.

Jeff, the consensus has been that I will be ok with one pickup??? typical use < 7,000 rpm, probably a lot less most of the time (streetcar).

Andy, the cover looks great.. however I think the issue is that the pump is too thick, so a thinner cover will help but may not solve the problem.

Are there any other HV pumps available... Indy..? ..
I need a really good pump but don't have the room! sigh.
Must have 1 x external feed line (can use block if needed), and provide for a remote filter.

Is the standard hemi pump up to the job of supply very high output street engine...?
