I recently read an article about putting an electric fuel pump on a 6.2L and decided to give it a try. WOW...I was having trouble before hand with my truck starting and blowing heavy black smoke if it sat for a few days. Now it fires right up and I no longer have to put my foot on the pedal to keep it running when it's cold. I put it in right after the fuel tank, left the mechanical pump still in place, and wired it to the ignition. I'm real happy with the way it works. The pump only cost $30 bucks at autozone, and about 1 hour to put in (with wiring and all that). Also, if you have ever run out of diesel in your truck you know what a pain in the A@@ it is to get started with only the mechanical pump working. With this electric inline, it should be a lot easier. 85 Blazer on an 82 chassis, 6.2L Diesel, ORD flip, 35's on a 4" lift.
