Thank you,
I'll check out the product at West (and I don't mind "being careful" while
filling if it can get me another 20 miles or so of range.
The previous owner said he uses one tank until empty then he knows he has
enough to get back. Good idea except it's almost 12 miles to the pass
before I even start fishing in the gulf. In other words, a 24 mile round
trip to the pass and back @ 2mpg, uses up one tank if I put in only the
12gal the prev. owner suggested.

West marine has an inline vent check valve that uses a float to close it
when the gas reaches it. I put one on mine to try to cure a similar
problem. Trouble is that now it comes back out the fill line if I'm not
careful.

Does anyone know of an "inline" product that would act like a check
valve,
would work in a horizontal position, and fit my 5/8" id vent hose. I
have
saddle tanks and the vent is only 4 inches or so above the top of the
tank.
When I fill them full (two, 18 gal tanks) I wind up with spilled fuel
out
the vents, all down the side of the boat (and in the water).

I was thinking of a pcv valve reversed, but even that seems to want to
work
only in a vertical position.
Thanks in advance.

There use to be a product that you stuck to the side of the boat under the vent
opening while fueling. It would capture the spill. There is also a whistle
thing that you can put in the vent line at the tank. It is suppose to work by
whistling until fuel gets to it, I've never seen one but several people swear
by them.

Why is there a problem with routing the vent hose above the vent opening then
back down?

I only have about 3" from the top of the alum. fill and vent tubes (to
attach the hose to) before I reach the underside of the gunwale. The vent
hose currently does immediately take a bend coming out of the tank and goes
down an inch or so to the fitting through the hull.

I think I may have found the answer on Perko's website--a combination
fill/vent with an anti-surge valve built in. I'm going to call them Monday.

For who's ever interested. I realized that about 18" forward of my existing
vent there was a 2" wide x 6" tall raised area of the gunwale. I purchased
a $17.00 "anti surge valve" from boaters world, 6' of hose and ran the vent
hose forward of the port tank and up, about 2' total. This allowed me to
position the anti surge valve at about 45 deg and come off the top, looping
down and back to the original side vent. Put in 15 gal in the 18 gal tank,
trailered and rode in the gulf--no sloshing! Nxt day put 3 more gal in the
port tank (full) and repeated. No sloshing or leaking down the side of the
boat whatsoever.
Thanks for the suggestions to all
