Has onyone ever installed a "Cackle Cure Kit" and if so what are your thought, Opinions, Likes, Dislikes, exp. an decrease in engine noise, was the kit worth the price,??? Etc,etc, etc.

I'm wondering why a fuel line connected between #1 fuel port & #8 fuel port wouldn't accomplish the same distrbution of fuel and increase the amount of fuel for #8 after the engine has been running for a short time.

The reported reason for the kit is that #6 Cyl fires and uses most of the fuel in the fuel rail and causes the starvation of #8 Cyl which is the next Injector to fire.

In theory: If there is 70# (or what ever) of pressure in both fuel rails and the driver's side rail is using an excessive amount of fuel because #6 & # 8 fire one after the other. This rails fuel supply enters this rail in the front at #2 Cly. Now the Passenger side has on abundance of fuel because it gets its supply from #7 Cly position on the Passenger side and nothing is being demanded from it at the moment.

Now, there is no bleed off of either of these rails so as the drivers side is being depleted by #6 the excess should, under its 70#'s of pressure flow to the drivers side as it is the least path of resistant adding more fuel for
Cyl #8.

What do ya think?

Cackle isn't normally associated with the single shot motors. Mechanical pumps and little injectors are loud, but reliable.

 

yeah the cackles stuff is mostly for the Superduty becuase they have a dead headed fuel system. On our trucks the fuel is feed into the rear of the head and flows thru to the front to FPR. on the SD's the pressure is regulated on the return as well but it is not a flow thru design. The fuel is fed into the cylinder at one end or the other and the other end is sealed. I think the passenger head on a SD is feed in the rear and the driverside is feed at the front.

 

Well, I'll be danged. That was a lot of thukin'and typen fer nuttin'. Hmmmmm

Well, what did you think of the theory, would it work? or would you
(if ya owned a SD) have to by that $100+ dollar kit?

Thanks fer taken the time to reply.

Will increasing the fuel pressure on an otherwise stock superduty cure cackle? I don't see how it could. With a dead head fuel rail all increasing the pressure will do is shorten the lifespan of the pump.

 

I think you read it wrong. By installing just the X-over line the pass. side rail is full and would increase the supply to the drivers side because #8 Inj fires right after #6 which depletes adequate fuel available to #8 Inj. The pass. side will automatically flow towards the path of least resistance.

This line just connects the two (2) fuel rails and does not connect to the filter, the FPR, nothing, just each other. The stock fuel supply enters the drivers side rail on the drivers side in the front (#2) Injector and on the pass. side it enters that rail at the rear (#7). I think that it will assist both rails to maintain a more constant pressure at all times.
