Snorkeling my 450ES cost less than $30 from home depot/lowes etc.. IT took me longer to think of designing it than to install it.I didnt even have to jet it untill i put exaust on it,thats when the 2 together needed a fatter jet size....P.S buy lots of plumber goob(clear)and use on internally and external connections,dieletric grease on plg boot and coat coil assembly.I also found that putting a small screw in the end of float drain hose helps alot(sucking in water occurs and makes idle stumble sometimes)GOOD LUCK AND BE CREATIVE...
