Fuel delivery

[tsubaki]

Had to figure changes to the fuel delivery. I didn’t want transfer and shutoff valves but can see they were necessary. If I could find 2 plastic 3/8 barbed shutoff valves, that would make me happy (the same thing is readily available in ¼ at lawnmower repair shops). These people have them but are in Ireland and have no prices.

I’m a big advocate of using things that are readily available so as to be easily replaced. I had to go with the normal three position fuel valve.

The location left a lot to be desired but I ruled convenience over looks. This location didn’t eat up room to the water seperator or create hose routing problems and is reasonably protected.

Cut a small piece of Starboard to use as a spacer to bring the handle close to the backsplash wall



Cut a piece of material and stamped the valve locations on it. This will also slow the possibility of damage to the handle.

Nice job Tsubaki

Nice Job!!!

Make sure you put some anti seize on the handle and handle screw or you never going to get them off again!!

I have had 2 of them valves and they corrode big time! Paint the handle with clear or color you want to help keep it from getting to bad!

I have a 4 position as I switch from 3 tanks.

Is there any way you pull fuel from both saddle tanks at the same time to keep weight evenly distributed?

Yes but you can't depend on it, it will take trial and error also some compromise as to valve locations and hose routeing.
In the instance I have finished you can draw between two tanks by putting the switch half way between P & S.
This will not be perfect but feasible.
Correctly done both hoses must be the same length and fastening manner to achieve even flow rates. No hoses coiled or riseing or falling different than the other.
Best location would have been the forward center backsplash for the valve and then run to the filter and motor.
I was unwilling to have the valve at that location for fear of damage so I compromised correctness for a more utility aspect.
I expect to always be adjusting the valve handle to get reasonabily close or just run a while on one tank and then swap to another.

Bad idea, running with valve halfway between, in my opinion. You'll be pulling fuel through two smaller passages as opposed to one of the proper size. At best your going to be working your fuel pump harder, at worst you'll be running lean. Running lean leads to the "big bang theory." :o

Run the valve open off one tank in my opinion.

[Skools_Dual]

if you want to run 2 at once just put 2 inline cut off's and then open what tank you want open 1 for 1 tank or both for both tanks and place a tee after the valves thatway it pulls from what ever valves you open.

[macojoe]

there is no good way to do it, I tryed them all!!

Best way is to change tanks when you want or need to. And what you have done is perfect!!

[Blue_Runner]

I agree - run from one. I used a valve just like that one with my '73.

Nice work Tsubi!
