Fuel System Idea

[spoonfedblue]

So I know there are guys out there running a regulated return, and guys running an Airdog 2. I see the general idea is that you really only need one or the other, but not both. (Unless you run a pusher pump with your regulated return)

My question is this: Has anyone played with the idea of supplying both ends of the cylinder head with fuel? Essentially creating the "deadhead effect" in the center of the head, rather than the end. Obviously some custom plumbing would be involved, but I don't see why this isn't possible. That way, an Airdog to could be set at your desired pressure, and it's basically it's own regulated return. Since both ends of the rail are getting fuel from the pump, no uneven pressure at one end or the other, or am I thinking wrong?

I don't have an answer, but I too have wondered this and interested I'm hearing thoughts on it

Of course it can be done But I wouldn't do it with an AD. I would use a high flow high pressure pump since you are going split the fuel path 4 ways. Come off the high pressure pump to the FPR in a flow through setup into a 4way manifold and then to the heads.

That is essentially what Diesel Site's HPO Delivery System works. It feeds both ends of the HPO rail.

Having said that I really don't see any advantage to doing it with the fuel system.

I see. Well, that answers that! Thanks PGreen, you always seem to come up with the info I'm pondering, when I either I ask for it or stumble across it.

IS THIS WHAT YOU DID PGREENSVT ? I drew this and was wondering if this is what you did ? i set airdog higher in psi so fuel would pass through heads and use regulated return

No but that is the way a normal RR system is done. I will draw up a pic of my fuel system design this afternoon for you. Right now I have to go back to sleep.

Ok This is what I am doing with my fuel system. the onl changes from it's current configuration is the addition of the Fuelab pump and FPR.

That is how I plan to run mine when we pull the cab. I have all the parts. The regulator I will use is an adjustable one that came on the boat generator...Westerbeke

One thing I have been looking into is polishing the fuel while it is in the tank. We do this on the boat

Are you sure that will handle the fuel pressure? I would doubt it.

One will never know if they don't try

You have another idea would love to hear it
