There are two hoses – big one is the suction, little one is the discharge and yes one is in front of the other in the photo. Pump is an OMC pump I bought over 10 years ago – pump was similar to attached pic from Marine Engine – not sure if that was this exact one. Could try flipping it – I may have inverted it when I reassembled with the new powerhead. The hose configuration is the same as I had when it worked on the older powerhead but the cap can rotate on the base if I remember right. I can see where dual filters in series could cause an issue… I like the clear one since I can see when gas is going though similar to the old glass ones.
