OP, how old is that cover?
I've used over 50 Milidon of the older pump covers over the years and never had a problem like your having with yours confused
I have three motors with the new style pump covers for the remote mounted oil filters, one is being used on my bracket engine now with no issues so far, one is on a customers 800 HP pump gas Hemi motor that came off a engine dyno last week with no issues shruggy
I do have one motor that has the Hughes brand single piece pump cover with the oil filter mount built onto it with no issues either shruggy
