ssdieselsupply.com......walt is a very good guy and can get you thru anything. 95 should have the upgraded water pump on it but if not might want to do that. Hot glow plugs also. Since I put them in I have never had to plug my truck in. I have a 99 that had a few issues that I had to work out but after $15,000 on the truck (abount 7 years ago) and $2500 in the truck with parts from walt I got a truck that runs with my dad's 03 dodge and get's 14 m.p.g. (crew cab, 4X4, dually).
What size truck and what gear ratio. A lot of guys that own the 6.5 in the 1/2 tons and 3/4 tons are getting mid 20's out of them.
