Re: Oil pressure problems, maybe.

One other thing on the fuel could be an older pump. If you are running fuel containing ethanol thru a pump that still has old type rubber, the rubber could be deteriorating and will soon fail. If you do not know the age or type rubber the pump rebuild might need to be done soon before it leaves you stranded.

I can't tell if that is a ceramic or paper element in the factory type glass bowl filter under the air cleaner. If ceramic, those can have problems with flow if gas repeatedly dried in the bowl and the old gas and varnish plugged the small passages in the element. It can be hard to determine if there is a problem because air will flow thru the element nicely but fuel can be restricted. If the pump is putting out the correct pressure and rate, if an air bubble doesn't get smaller or never completely disappears and the fuel in the bowl is continually at a low level after a period of running then the flow thru the element might be suspect.

The rubber hose between the line on frame and pump can also cause flow problems if it is old or was twisted during a pump install.
