I know gauges were supposed to be the first thing I put on my truck, but I figure better late than never. I am thinking I like the pillar mount gauges best. I want a egt, boost, and a fuel pressure gauge. I have already had to replace one bad lift pump. I want to use all the same make and type of gauge, but can't find anyone who makes all three that I like the design of. I like the Isspro EV series. I was thinking I would use the 40psi boost gauge, and then use the 15 psi boost gauge for the fuel pressure. I know it probaly isn't compatable with diesel fuel, but we use gauge isolaters all the time at work with chemicals that eat everything except for titanium and platic. I would mount one close to the filter and use an inert fluid to the gauge. Anyone have any thoughts on this? Any other suggestions. It wouldn't bother me that the gauge wouldn't say fuel pressure, I would know what it was for. Thanks
