What do you think caused the tip to crack? Are they upgraded injectors?

Sorry for the bad news.
Will you have to eat the cost of the injector?
My truck has been down for 10+ weeks.
Hopefully on the road this week, when I read your thread I got a lump in my throat.
I am also getting new injectors, but I went with stage 1 casserly

It is good to hear that he is taking care of you.
Do you know what caused the injector to fail?

No idea just a fluke air or water in fuel will cause a nozzle to come apart but i have a spin on fuel water separater full ss braid fuel system with fuellab regulator 1/2 feed and return lines with 3/8 lines going into heads with fuel sump so i dont think i have ether of those problems theres no easy way to find out if i do have air in fuel but my injectors are alot quieter then my old ones which is a tell tail sign of air in injectors

Where is this located in the fuel line? Do you have a fuel pressure gauge? I had one of these before the pump and it killed the fuel flow in high throttle.

I don't know Rich, he has dual SD fuel pumps, I'm sure he has the flow. Read about your tune up, sounded great, wish I was there, love to have someone go over mine like that. I'm sure I'm not the only one. Sorry for stealing the post guys.

I was looking at that and yet I was thinking loss of flow on the suction side can not be made up for with more pumping. Vacuum is vacuum, and it doesn't take much to pull the big handle on the porcelain tank. Since he's getting 60-65 PSI FP at WOT (assuming it gets to the sticks), we can leave that one aside for now. I'm just looking for root causes and everything has to be asked.

Good call on staying with the OEM pumps... that's how I'd do it, if I needed to put the spurs to those ponies.

Well one is oem one is airtex hence the 3-5psi drop would be my guess and fuel pressure is after heads and i have sump 1/2 line to 12micron fw separater 2 3/8in lines coming out of filterhead into pumps then into other filterhead with 2micron filter then 1/2in up to motor splits into 2 3/8in lines into each head then out back pf heads into regulator then 3/8in return line to the pick up which i made the return pumps are on a separate harness drawing straight from batteries
