Yea i did have a hard time finding the fittings.... Im sure if i spent more time looking or searched online i could of got the 1/8 to 3/8 barb nipple but it wasnt happening at the standard home depot... I found the 1/8 street 90 that threads into the case at home depot but the largest hose barb i could find was 1/4 ... so i used a 1/8 pipe nipple into a 1/8 to 3/8 adapter ... then i found a 3/8 pipe barb with female threads to screw onto the adapter.....more fittings then i really wanted but it works just the same... pics a little blury but you can kinda see what i mean
