Hi all,
I have a 1997 7.3 that I really havent done any major mods to yet, other than 4" straight pipe, intake and a few other small things. I am going to get an oring kit for the fuel bowl soon and replace everything because it is leaking. I was wondering if it would be a good idea to pull out the guts of the stand pipe and also pull and drill the fuel rail plugs in the heads, and/or modify the FPR spring while im working on all this.
Will i notice anything without injector upgrades? Are there going to be any negative side-effects from making fuel flow more easily?

 

only thing i would do is if it needs it is to shim the FPR spring

 

well i havent checked the fuel pressure, and dont really have a quick way to do that other than to install a gauge i guess.
Would you suggest the bb shim trick? or should I just get a spring for it.
Also wondering if you folks with the e-fuel and injectors had to drill out your fuel rail plugs?
Im not trying to go crazy on this truck with mods or anything, but would like to bulletproof it and maybe get a little more power if its cheap and simple i guess. I gotta use this thing for work like most of us do, so I dont want to build some race truck.
Also I have a lot of morons that work for me driving both my trucks and dont want to give them a chance to tear anything up

also, thanks again joebob for the quick reply. I value your advice as much as any of the diesel mechanics or other powerstroke performance folks ive spoken with.
It seems like you know what does and doesnt work with these trucks

 

You can check it with a tire pressure gauge.

I have E fuel and have had 200/0s and 300/100s, I didn't have to drill anything out but when you do E fuel you put in new fittings in the front and back of the heads.

 

I would check the fuel pressure before shimming the fpr

 

I am a freaking moron. Had no idea there was a valve right there on the fuel bowl.
Checked the pressure today, bounced around from 50 -60psi at idle.
Would I benifit from a spring or shim? Or should I just leave it alone

 

I would leave it alone, it is were it should be at those pressures. Some people shim it because the pressure is to low (30-40) PSI but its not a solution to the problem, when your pressures start getting that low its most likely your fuel pump getting worn out and its just going to get worse with time. If your running stock injectors and a chip you will be fine. You start running into problems once you upgrade to bigger injectors. If you plan on going to bigger injectors I would recommend swapping to a electric fuel system.
