Contrary to all of you who are out on their boats having the time of their lives, sailing or tackling new projects, I am 5,000 miles away from my boat, which sits melancholy at its dock
in San Pedro, California
But even far away, I do get to undertake projects - just don't get my hands cut up and bruised.
Enough of the nostalgia -
After a sailing trip this summer, our engine
went into a coma - clogged fuel
filters ! The aluminum
tank was a haven for a huge colony of microbes. We replaced the primary and secondary filters, and all was fine again.
But the problem is not solved
I need to open up an inspection
port to get the sludge out. Then, I want to install an independent on-board fuel
polishing system - the kind you make yourself with a Walbro pump and Racor
My question concerns the access plate - It will serve as an access port as well as base for the feed and return lines for the re-circulating system.
Originally, I was going to use a1/4" aluminum
6061 plate (6" X 6"). Tap 2 holes into the center for the fuel fittings, tap and screw into place. But then, I began reading about the incompatibilities of bronze, copper, stainless, and aluminum.
So, instead - what about using Rigid a High-Density Polyethylene sheet (maybe 3/8" thick) ? It would solve the galvanic incompatibilities. I can still tap threads into it for the fittings, goop them up to seal properly, and I can even attach a back nut to ensure a better fit.
Hope this is not a dumb question ?
Thanks to all.
