RE: Fuel Polishing system anyone build one?
The dual 500's on the left are only for the engine and genset supply (30m and 10m). I only polish thru the single filter on the right (30m). I didn't see the need to scrub it all the way to 2m, so mine is and either/or rig. You scrub or filter to engine. I can't switch over to a backup filter while running. I still need to install a 2m filter before the genset, but I'm not in a hurry to do that. It can deal with 10m fuel for a while. Come to think of it, it's the same with the main. Only sending it 10m fuel for the time being until I can get a 2m for the CAV filter. I guess I found my project for next weekend. :-(
Thanks for the props... I had a good time building it. Yours looks quite complex and I'd like to see some pics of it. TBH, it's very much like how my own designs looked in the early stages until Rick intervened and neatened it up greatly. Complex is bad.
It might be just me, but are you only dumping the returns from both engine and genset into one tank? My OEM rig was like that and I thought that was screwy, but once I routed it thru a selectable manifold, it gave me the ability to use the scrubber as a fuel transfer system as well. That's another reason to go with a 60gph AC pump. That Walbro pump has a shorter duty cycle before it needs a rest. The AC pump/motor I am using can run for days if I need it to.
BTW... Those are my "work-on-the-boat" jeans. They are old, tired, and stretched out. With all the bending, stooping, ducking, twisting and general contortionism, wearing a belt is uncomfortable for me in the engine bay. Sorry... Hey, at least I had ON underwear! Consider yourself lucky.
