Well, here's some of the stuff I've heard:
  1. Eliminate air by sealing the tank side connection to the fuel pump
  2. Ford will tell you to install a LL in #8 injector hole
  3. Increase HPOP oil pressure
  4. Some have installed a crossover fuel line between the heads (firewall side)
  5. Use an additive (I personally like Diesel Kleen grey bottle - available at wally world)
  6. Do a WOT run to 80 at least once a week (gets the air out the fun way)
  7. Turn up the radio (cheapest )
Seriously, cackle can be a real bad issue. Contributes to cavitation (that ringing of the cylindar wall). If you have a bad case, you're loosing hp, fuel mileage and performance. IMHO getting the air out of the system will help a lot, use some fuel treatment also. Good luck, this can be a very long journey! Better have some brews ready! :HappyMugs

its so annoying, actually embarassing. would increasing fuel pressure help as well? i wonder if maybe my injectors are worn from the mileage and compounding the problem. my friends truck and my truck have like a metallic knock at idle, it seems like a common noise, its nothing serious ya know, but wtf is it? anyone else experience that?

isnt there a cross over pipe for the for the fuel to? or am i confusing that with the hpo cross over. how do those hpo cross overs work anyhow, just for cackle or what?

one thing i definitly noticed is to not run below a 1/4 of a tank, thats where the noises are at their worst.

that looks worth while, inexpensive too. i noticed they have a regulated return kit that should really help, its expensive tho but might be worht it.
i have a brand new aeromotive fuel pump, its not an a1000 its a step below that, i think its rated for 800hp, i wonder if it would be worth it to install that in the truck.

It wouldn't help with the noise. But a pre pump mod would. That is where you replace the factory hose fittings with diesel rated fuel line and good clamps, even double clamping. The factory fittings let in a small amount of air.

Seems theres been alot of aftermarket pump failures, theres nothing wrong with running a stock superduty pump at all, I still am and still will be.

A regulated return will help out alot.

The crossover is my next mod, soon as I get some freakin money! My truck has the same knock you are talking about, and has had it since it was bought. I don't think its hurting anything since it's always been there, but I would definitely like to get rid of it, especially for 65.00 or so!

A crossover wont get rid of the problem, the problem is with the fuel not the oil. A reg return will help alot--save up for that instead.

Mine quit cackling when I installed my DP Tuner chip. Seems to have something to do with having a stronger or more positive injector pulse.
