Fittings For Fuel Tanks


Randell 'Randy' Kocurek

Bud,
Have your nice new tanks all coated and ready to install. Also have the various fittings referred to in your manual. I want to be sure I have them right before installation.
I suppose the pick up line goes in the inboard front (forward) side of the tank and the fuel return line goes into the front outboard side of the tank. I suppose the 1/2" line is the vent. I suppose the cut off valve fits fitting at the tank that connects to the fuel line leading to the engine.
How am I doing?
Please confirm or otherwise straighten me out.
Thanks. Love the tanks. I think they are going to be perfect.
Randy

I will let Bud answer your question (But you have described what I have done less the coatings) Just remember the fuel pickup has the long tube inside and the return and vent lines have just the connections.
1.) I installed a flush 4" bronze screw type deck access plate over the front end of the tank which allows me to have the shutoff valve on the top of the tank and accessible from the cockpit.
2.) We also put one of those 6 amp inline blowers on the back of the wooden bulkhead and have it pointed out the 4" hole which allows me to remove the heat in engine room fast; 1 min run gets most out. (We did not use ducting but this type of fan has the blades in side the short tube = less issues with it catching things, hose, wire, etc.)
3.) On a cold watch with the engine running you can open this port up for some personal heat, really nice when it is needed.
4.) If you run the fan while motoring in a hot climate it keeps much of the heat out of the cabin.
Hope this helps.

P.s. the hole also helps when connecting up the hoses or reinstalling a fitting.

Norm,
Thanks for the notes.
Are you saying you cut an actual hole in your deck for access to the tank shutoff valve? Not sure I understand. Why would you need to have the shutoff valve available from the cockpit? Seems like it would only need to be shut off in an emergency. Again, I assume the cutoff valve is in line to the engine intake. It could be mounted further down the line, I was thinking. Ah, the fan + 3" exhaust hole, now that seems smart. I really like that. Just not sure I like it enough to cut two more holes in the deck. Thanks for the feedback.

Oh Norm,
Another thing. I was wondering alot about that long tube inside the tank for the fuel pickup. Seems to me it could get clogged, and if it did the only way to get it out would be from the top (trans: hole in deck or tank removal, I suppose). So, did that have anything to do with your idea for the 4" deck access plate?
Thanks again.
Randy

Randy:

Why? The reasion I have the valve accessable from the cockpit is; (shut off time) 1.5 sec. hole VS 12 sec.through the engine room (Fire issue as well as hose rupture) my valve is located on the fitting exiting the tank.

The answer to your second question is Yes

I also only have one tank = one hole. Only issue I have had is to close it up in rough seas. Normally I leave it closed except when motoring or cooling off the engine room.

do you already have both tanks?
If not the second tank could be set up to have a 4" or 6" deck plate for both the filling of the tank and access to the fittings (Custom designed tank) (a Note: one of those books require that over filling of a tank not go into the boat and not go over the side if the nozzel is left running for 5 sec.)

I will put one more item on the arangement here: in one of the other posts someone noted that the vent could be sent in to the cockpit I think this is a bad idea (ever had fuel and water on deck = really realy slick and could = loss of life under the wrong conditions). And for a valve on the vent line: I believe this would be a bad Idea, you could forget to open it just when you needed it the most.
I have a vent loop tied up just under the inside edge of the cockpit well then run up as high in the bulworks as I can before going down and connecting it to the vent on the outside of the hull, this has seamed to cover both tacks and one knockdown (starboard side) without fuel loss or water gain.

Happy plumbing:
Norm

P.s.
Bud may have some good advice as he has seen many W32's and I believe he is a realiable sorce for the proper design.


Randell 'Randy' Kocurek

To answer my questions for future reference of the group, I contacted Bud. Essentially, on his tanks, the fuel pick up line goes in one of the two forward fittings atop the tank and the other forward fitting is for the return line. The vent line is back by the big 1 1/2 in. fill line, near the overboard vent. As for the placement of the valve, it goes on the fuel intake line to the engine. Since I have two tanks it is more complicated with Y valves and such. I think I understand but not well enough to try to explain it via email.

By the way, Norm,
Thanks for the great input. Yes, I already have tanks, thanks to Bud. I'll be taking all your ideas and experiences into consideration because as soon as the weather clears from Dolly, it's time to move to installation. Decisions, decisions...
