What is the best fuel regulated return system? Fuel bowl delete or not? Im trying to get rid of this annoying cackle. Thank god for tax returns haha. Any tips will be helpfull. Thank you.

 

hello and welcome to fte. I have riffraffs frx, hpx and driven diesel pre pump filter. look for Hutch, Harpoon mod. all this took care of it on my truck.

 

Hutch and harpoon mod is the call. Air in fuel should be prevented, not removed. FRx and regulated returns don't protect the fuel system from...

• pump cavitation
• reduced pumping efficiency
• diminished fuel delivery or total loss thereof

FRx can only remove air from the fuel rails after the air has had a shot at your injectors - but it's still good to eliminate deadhead.

 

What is "cackle"?

 

Good article, "Hutch & Harpoon" mod;

Welcome to guzzle's In-tank Hutch Mod Web Page

I have had to pull and disassemble my pick-up assembly four (4) times to clean my bronze 410 screens. Fortunately, the service bed on my 550 is high enough so that I can crawl under my truck and access the Fuel Pick-up hatch by leaning front to rear, over my rear axle.
Of course, "Murphy" always requires this service interruption at the least convenient occasion.
I am going to add this Mod to my list.
Thanks "guzzle" !

 

here is what it sounds like. it gets louder as the engine warms up this is probably the loudest it has been. thanks for any replies

 

And also if i open that valve cover and its just a normal AB injector. can i replace it with a AF (LL injector) and that will cure this problem.

 

Being new to diesels (November), and having a 2000 7.3, the truck is noisy on the outside, and I just figured that that sort of sound was to be expected from the older model trucks. Your truck sounds about like mine. Should I not expect so much "diesel machinery noise"?

 

Truck is gonna be loud but when I hear something that sounds like a mechanical issue. I get worried. but most of the time it's just cackle... if I'm not mistaken "cackle" is air being forced in the injector and makes that noise. But before I start doing fuel mods. I'm just gonna pull my valve cover off and see if my #8 injector is working properly and to alsoffers see if it is a long lead injector. The long lead injector was made by ford to cure cackle.

 

is it better to just remove the filters in the tank? I've seeNight it both ways just wondering how u did it.
