I am sorry I don't have a picture at this time, guess I will have to try the digital camera for the first time this week end.The set up is very easy and only takes a few minutes. The fuel filter is with in 7 inches of the PVC valve, but above it and at around 45 degree angle. If the oil is coming directly from the engine at that point there should be no problem allowing it to flow back down to the engine. I made the check valve from (2) 5/16 1/4 npt brass barbed fittings and a i/4 npt coupling.I used an 82 deg. countersink cutter to form a seat on one fitting which the 1/4 inch ball bearing could seat on.I used a 1/4" nylon washer for the spring to rest on and the spring would apply light pressure to the ball.This would allow the check valve to be placed in any orientation and still be functional.You can purchase check valves,I just had alot of brass fittings and have a habit of collecting springs in case I want to make something.So far so good, I am happy with the results.Good luck![8)]
