Hello

Well like the subject says I own a GMC sierra ext cab long box K2500 6.5 TD I'm thinking about upgrading the cooling to 97 style pump and doing some other mods. A google search brought me here so I look forward to checking out the forums.

welcome 1st mod would be pmd, #2 mod you need to do is OPS mod.

Welcome!

Exhaust and gauges should follow, it's best to make it reliable first then let it breathe before adding fuel.

PMD mod was first thing I did. Why the Oil pressure switch mod I may have to look this one up.

94-95 the lift pump is run thru the OPS while the engine is running. Very common failure point
