I've been very polite to your buddies.  I also have bought many many parts from Summit over the last 25 years or so.

Ditto, not polite sounding all the time.  Sorry.

I don't however share your desire to spend "big bucks" on parts that don't work as advertised and just eat it when they don't.

Nor do I but I do buy parts I know will work and not just something because someone else says they are great.  You have to do your own home work.

My beef is with Milodon, I'm just trying to enlist the help of Summit to get them to take the pan back.

Then take it out on Milodon, as I said, Summit will take all parts back as long as they aren't ruined within 90 days.

It's easy to come off as arrogant in an email.   You can neither hear the tone nor the frustration of all the hours of work being in vain.  It's all subject to readers interpretation,  One guy would say "I understand" the other "he's arrogant"

This is very true and I may have jumped the gun but it's just how it seemed to come off.

Back on track here, I can't pump a 6 quart pan dry with the same brand HV pump as I'm using now on a 10 quart pan.

Sounds to me then the pump is bad not the pan.  If it's not pumping, that shouldn't have anything to do with the pan.

How do you explain the manufacturer telling someone to drain 2 or so quarts out of a 10 quart pan and try that?    They are trying to blame it on the pump bypass??  Am I missing something here, how does taking oil out of a pan fix a bad oil pump bypass?

Which manufacturer?  The pan or the pump?

Summit says try a stock pump.   If I'm pumping the pan dry why would you take oil OUT?  If it's a pump bybass why would you take oil OUT   Why would you go to a stock pump and not a new HV pump if it's a bypass?  Does this sound like crap and a run around to anyone else or is it just me?

Because it would eliminate that part of the upgrade to the system.  Only stands to reason, you make one upgrade or part change at a time so you know at what point the system fails.  It works.   I'll stop now.  Good luck and no hard feelings

...why would you need a high volume oil pump in the first place?  Seems to me that you would be pumping all your oil out of the pan and it doesn't have time to return for proper circulation.

Generally speaking and assuming all else is exactly the same in a given engine (engine clearances, oil type, oil temp, oil pressure, etc) the high volume pump will not pump any more oil than a standard volume oil pump and therefore has no greater ability to "pump the pan dry." The HV pump simply has the ability to send more oil if and when needed, which can be a godsend in a sustained high rpm marine application engine.

LO

Thank you!   And no hard feelings.  I think it's great to have a spirited discussion.  It helps
unload the frustrations and gets some great ideas going for a solution.

Thank you all again.

PS  I don't want anyone to miss the part that today with around 7 quarts of oil this engine
DID NOT LOSE OIL PRESSURE RUNNING 5000 RPM'S.   I just ran it up and backed it off.

WITH THE HV OIL PUMP!

IT WAS NOT THE OIL PUMP AS MOST ALL OF YOU SAID ALL ALONG,  SO YOU CAN GIVE EVERYONE ELSE
AN "I told you so"   

SO A BIIIIIG THANK YOU.

Sure was a great day on the lake,  I hope everyone had a great holiday.
