Hi everyone.
I am kind of new to this so I may have a lot of questions. I hope you will be patient with me and thanks in advance for all your help.
Now for my question. I hear a lot of questions about power loss and replies of changing overflo valve. Just what is it and where is it found.

 

P7100 pumps on 2nd gen trucks, valve cover side of the pump, in the front. there is a line attached to it with a banjo fitting. do a search and there are some pics of im sure. There is a vendor here that can get you one for $50 or so.

Replacing the OF valve is a five minute one wrench job if you don't drop the sealing washers, stuff a rag under the valve to catch a falling washer. Remove the old valve and put new one in it's place. Occasionally the notch in the manifold you see to the left of the OF valve in the picture needs to be filed or ground a little to allow the old valve to be removed. Don't bend the return line to remove the valve, it will make it very difficult to line it up again. New style OF valves don't always have the retainer on top that says not to remove, don't worry it's just a design change.

The object in the lower left corner is the oil fill cap.
