LBZ regulator in an LB7

[littlejeepr]

Well over the last couple of days i finally got my fuel pressure reg changed out and boy was it a pain. It will take probably the next week for my knuckles to heal:eyebrows:. Outside of forgetting to plug in the fuel press sensor and fighting the one fuel line that is in the way becasue of the different connectors on the LBZ reg to the LB7, some plug just the new one is up 90. For all of you that have already done this i feel your pain. The truck is running good now I just need to fix my fuel table so when i decell and stop the truck doesn't chug a little. Hopefully a couple days of driving that way doesn't hurt anything. If anyone has a better fuel table than the couple that i have found and you don't mind sharing it let me know.

Thats odd, my plugs where the same.

I took it for a ride and when i came to a stop it idled funny then went back to normal, then i drove away. Is it going to hurt anything considering that my fuel pressure at idle is 6000 and what it is calling for is like 4900 at idle. that is the thing from what i have been reading in many posts is that it may need to be adjusted, and some people have adjusted it and some haven't i guess :noidea:

adjust it down. 4900-5000 is normal idle anything higher and it will lope like it has a big cam.

I went to my buddies house tonight and we changed the b1010 to the ones in this post will a lbz regulator work in an 2003 lb7? - Page 3 - Diesel Place, It seems to be good now fuel press peaked at 5100 and the lowest it droped was 4880 according to the V2 much better than before with the old reg. The old reg was up to 5500 sometimes 5800 then it would drop to 4000 sometimes lower. Well hopefully it all goes well now. I also have no more stumble in it when the throttle gets cracked it comes back down nicely without the bobble.
