Hi All,
Workig on doing cams, hybrid cam plate and high volume oil pump. I have a question on the oil pump assembly. The original pump had a groove for an oring. The new pump has no groove for an oring, pump is larger than stock. Just checking if an oring or gasket is evn needed to join the pump to the screaming eagle cam plate. Thanks in advance

 

which pump are you installing brother? that would help greatly

fyi..
my fueling 7060+ had an O ring between pump to cam plate.. which it too was larger than my SE oil pump

 

25284-11 screaming eagle cam chain tensior plate upgrade kit with high volume oil pump

 

I have never seen in person, or installed the Screamin' Eagle kit #25284-11...... BUT ....

Looking at the install instructions, namely figure 8 and table 2, they don't show nor do they list an o-ring between the oil pump and cam plate... So I suspect there is not supposed to be one...

And even though they are not part of the kit, DO NOT forget the 3 o-rings (#11x2 and #9) in this diagram.... they are important!!

If your old ones are in any way suspect, get new ones....
