Hey everyone I have a few questions, if ya'll can help. I have a 98. 5 Quad cab Cummins. First AIR FILTERS, I understand that the BHAF is the best way to go right? Is this just basically and open mount where the old box is replaced with the open mount which holds the filter? Second GAUGES, I have a Pyro, and a turbo boost gauge from my 93 which I am going to put on the 98. 5, I also have a (are you ready for this) a DIRECT CONNECTION fuel pressure gauge (outside mount) which I was thinking of putting on the hood, it goes to 15lbs. Is that enough? and where do I hook it up to the fuel system for best results, still reading about this lift pump situation, so give me some pointers or help me find the info on here I need to read. Third EDGE EZ box, what kind of money should I pay for one of these? and any sugguestions as to where to purchase them, I have seen them on Ebay, but wasn't sure what the price should be? Last, MAX TIRE SIZE, on a 2WD I understand that 285/75 is as tall as I can go, is that correct? I looked at my truck today, it has 245/75s right now and it looks like the 285/75s might rub? Thanks in advance for your help. Richard Hawkins, Redbeardhawk
