Question on Mounting a Gas Fuel Fill
 

I'm hoping that I can gain some advice again. I'm in the process of
replacing my deck and stringers in an 18 foot Regal, and want to add a
below-deck fuel tank as part of this project. This is a gasoline fuel
system supplying a 90HP Yamaha Outboard.

I've settled on a design and supplier for a custom aluminum belly
tank, but the most clearance I can gain between top of the tank and
bottom of deck is about three inches. I've located a Perko combo fill-
vent w/angled cap, model 540 (Part Number 0540DPGCHR). This has the
hose connector tube angled at 35 degrees to the mounting flange/cap.

Combined with an angled fill tube on top of the tank, I should have
just enough room to run a connecting hose between tank and deck
mounted fill. Since there is such a limited clearance, I plan on
using the fill's integral vent for a spill line, piping it to my open
bilge pocket, and venting the tank directly to a flame-arrestor vent
higher up on the hull.

The particular fill is hard plastic with a chromed bronze cap. Due to
the limited clearances, this fill will be flush mounted on the deck in
an area that gets walked on. I considered recessing it and putting it
under a removeable deck plate for protection, but don't see that I
have the clearance between deck and tank to recess the fill.

My question: Is locating the fill in an area where it gets walked on
a fuel safety hazard? Are there any issues I need be concered with
by putting this deck fill in an open deck area?

Appreciate any advice.

Thanks Dan,

I had read the USCG regs you included on my earlier post, but I missed
the section on locating the fuel fill. This pretty much answers my
question.

Use the aircraft type fill cap. Locks with a turn of a folding lever.
Definitely walk on them with no effect whatever. My car has one.

My cockpit sole gas cap allows a chance to catch drips. I use needle
nose pliers to open it. Be sure a ground wire connects filler neck to
tank and tank to sender to -V, 12 vdc ground, and not to lightning
discharge ground path.

Continuing thinking along tese lines, I bought a combo fill vent for
my sailboat. I called the manufacturer and asked if I could purchase
the fitting I needed to pressure test the fuel system after I get it
installed. They sent me the fitting right away, for free.
I have the Attwood 3682-1 in stainless. If you can, you should test
your fuel system at 3 psi and check it using soap bubbles like the
regulation says before you put gas in the tank. It can't hurt if you
do it correctly.
