From the feedback I've received from other M38 owners, I've decided to add a port/starboard pair of fuel tanks just ahead of the aft bulkhead in the forward stateroom. It's apparent that the boat can easily carry the extra weight of 40 gallons of fuel up forward, even with an all chain rode and a windlass. (One of the keys is to pull out the lead ballast installed under the forward end of the v-berth.)
The next decision is how to get the fuel into and out of the tanks. I'm considering having the fuel lines draw from the bottom ot the tanks as opposed to a siphon tube out of the tank tops. The tanks would then gravity feed to the filters and ease bleeding the lines should the extra tanks ever go dry (a definite probability). I've heard somewhere that gravity feeding gasoline is illegal, but that it's OK for diesel. Does anyone have information on this?
Also, is there any reason not to install only one deck fill plate & hose and then allow the opposite tank to gravity-fill from the first tank? If the bottom fuel outlet connections were tied together through a manifold arrangement, they would slowly equalize while filling.
Lastly, which is better -- feeding the engine only from the main tank and re-filling the main from the extra tanks, or connect the extra tanks directly to the engine via a fuel manifold?
Any thoughts would be appreciated -- especially from those folks who "have been there and done that".
Regards,
Jim
