I guess some MODS don't work foreveryone

Awhile back I installed a HX cross over hose on my 95 7.3. I've had intermittent problems with rough idle, and what almost sounded like a dead cylinder. A diesel mech friend of mine listened to it last night and said it sounded like a lazy injector or the pressure in the injector rails was low. After some brain storming, we removed the HX cross over hose and put everything back where it was originally, and low and behold, she's smooth and quiet again. It's kind of like firearms, some like certain ammo, in the case of my truck, it doesn't like the cross over.

Good news is she's running good and doesn't have to go to the shop. Speaking of the shop, if you have the shield plates under your rear fuel tank, make sure you clean the mud and crud from between them and the tank periodically. Anything that holds moisture in there will rust out the tank over time. It did on mine in a big way, $230 later that's fixed.

That's very strange. Is there any chance your crossover was not installed properly? Specifically, did you have the hpop supply line relocated and the cross over on 5 and 6? I have only come across one supplier that acknowledged the difference necessary for the 94-97 years. Mine sure made an improvement. Sorry it didnt work out for you.

My crossover came with very detailed instructions, and was installed as you described. I find it odd as well, as so many here have had good results, but mine just didn't perform up to expectations. There may be other contributing factors, and as time permits, I plan on researching that.

hi guys just letting you know the pain i'm going through with this 4" exhaust with the 4" turn down. i bought this from a friend that has a 00' f-350. he went 5". price was right! well i got the fire wall "moved" and this is where a porta-power comes in very haddy. but the bends are not the same the 00' has more room between turbo and the fire wall. so i'm in the middle of gutting and reangling the flang. i'll write back with pix when i'm done. pray for me

How long did you have the HX in?
When you installed, did you run the hose over the top or down thru the valley?
I had the same problem as you.
I had to drive it like i stole it.
What happened to me was under normal driving i could not get the air to bleed out of the system. Air stayed in HX hose (high point).
Drove it hard a few times then all was fine.
My install was over the top. Now i rerouted the hose down thru the valley.
