I have seen installations where the fittings are pointed down so that you can drain the system. I am going to put a tee at the bottom of each port. Pipe thread to 90 deg and 180 deg fitting, hoses will attach to the 90 deg fittings and a AN cap with saftey wire hole so I can saftey wire the cap to the tee so it will not come loose or loose it, I just may saftey wire all the fittings. When I drain the oil off comes the cap. I don,t want to lose a motor. The problem may be with the inside diameter of the hode you are using. I would check aeroquip guide for proper inside diameter of hose to use. They need to feel as they will not go on at all, you need to lube it up to get it on. You may get some expansion on the hose from the heat but I would think it would be minimal. Don't get me wrong but there are a few things that I would not DYI and this is one of them.
