Re: oil filters, again !
It looks like they just replaced the stock canister filter with a regular spin on filter. I'm only saying this because it appears to have only one line coming from the pressure side of the pump and then the return line goes back to the pan. That is how the stock setup is.
Although I could be wrong. If the line from the pan is going to the inlet of the filter and the outlet of the filter goes into the block, they could have one of those modified pumps to do 100% filtration.
