|  Fuel fill vent 
			
			I have a 75 v20 with 20 gall. saddle tanks, I am getting water in my fuel vent in rough conditions. any suggestions on how to correct the problem. FYI when I redid my tanks I mounted vents with the screens facing down. i did not put a clamshell cover, should I have?

			Is there another type of vent that does not allow water in

			Did you route the hose from the vent upwards towards the gunwale before turning downwards to the fuel tank? It's like installing an inverted p-trap. Also, have the vent angled at 45 degrees toward the stern.

			When I had my 75, I moved the vents up to stop fuel from leaking, andput clam shells over the vent to stop the water tfrom going in under way!! http://www.ebay.com/itm/SEACHOICE-SS...5SljiK&vxp=mtr

			Check valve in a vent would be bad... It needs to relieve both pressure AND vacuum.

			My vent has a full loop in it. Should it just be a hump like an upside down p trap?

			It's funny my fuel vent, bilge pump, and fishboxes drain hoses all had full loops in them. I took care of the drain hoses already but when I changed the vent hose I put it back the way it was. I'll fix that tomorrow. Glad I saw this thread since I plan on taking my boat to the marina tomorrow.

			Do like MJ said. Make the new locations above the rub rail and just leave the old ones in place so you don't need to patch the holes.
