New WVO fuel system design- Could it work ???
#2068414 - 10/30/04 10:05 PM Edit Reply Quote
I scored myself a bosch fuel pump today that is rated for 52gph @ 150psi
, and am planning on using it in a completely seperate WVO fuel system. Well
while trying to figure the simplest way to hook up all the plumbing, valves,
switches, sensors, relays etc, I came up with an idea to eliminate most all of
that. running a dual tandem fuel system. I will leave the factory fuel system
just the way it came from ford, except I will add a check valve at each point
where the lines go in the head. I will then rig up a similar setup for the WVO
using the ports on the back of the heads. I also found a mustang style pressure
regulator at the junkyard that has three ports on it. 2 that T at the
regulator, and then a return. I will run the veg oil lines from the pump, at
the tank, through my big Donaldson, to the pressure regulator, and to the rear
fuel ports on the heads. Essentially a dead head type system, like the factory
uses. I will set my pressure regulator to 80 psi, and wire my WVO pump so that
the nuetral lockout feed will disable it when in park, or nuetral. Now, when
the truck is cold, the Oil will be thick and not flow very well, but the #2
will be just fine, and the truck will run on it until the oil gets warmed up.
Once the oil gets warm, starts flowing and the pressure exceeds the factory #2
setting(around 55psi), the Diesel will start bypassing back to the tank, as per
the factory design, and the truck will continue to run on WVO. The check valves
in the diesel lines will prevent the WVO from backfeeding into the diesel
system. And similarly, the WVo regulator being set at a higher pressure than
the factory regulator will prevent the Diesel from backfeeding the Oil. Cross
cantamination solved. Again, when you go to start up in the morning, with the
truck in park(or nuetral for manual), the veg oil pump will not be on, only the
diesel pump. Then once you begin driving, pwr will be applied to the WVO pump,
but it will only begin to run on WVO, once warm enough to flow properly, and
cause the diesel to bypass. Now when you are where you need to be, put the
truck in park, and the WVO pump shuts off, pressure drops, and the diesel
begins to feed the motor again. Simply let the motor idle for a few seconds,
and shut it off. I will figure out how long it takes to purge, but shouldn't be
long. And even better yet, down the road when I do performance injectors, I
will have all the fuel I could ever need. . Allright, please poke some holes in
my system, I am all giddy right now, just seems too simple, I must be missing
something
