.177" vs .187" for the Bobcat part......
....what's the tolerances of the plastic insert in the pressure regulator? Or for that matter the production tolerances on a BB?
I think the BB mod is shade tree all the way, but hell, if it works it works.

Thanks Benny I'm gonna try the BB. My pressure isn't terrible anyway it runs about 55. I have a box of BB's that are 4.5 mm and I will look it up to see if that is .187. You guys are a great help.

Agreed that it's shade tree and the only reason I used the Bobcat part was that it was hardened for hydraulics whereas a regular BB is rather soft.

I would say NO. The only important thing here is that your fuel pressure is at an acceptable level. It will take about an hour to check it out IF you have the proper wrenches for the fuel lines.

Thanks for the info. npccpartsman. Right now I've got a more pressing issue with the FICM, it wants to go see Ed so I have to reconcile that with the pocket book. I'm reading about all the different mods i.e. Blue spring,egr delete, and so on to this motor and I'm wondering what I've gotten myself into.
