I have a '98 Suburan with the 6.5 diesel. The fuel pump went out on it a while back, so I went and bought a replacement--an AirTex. This particular filter mounts on the frame rail and is easy to access, fortunately. After installing it, I primed the system and took it for a test drive. The truck died less than a mile down the road. After re-priming the fuel system I started it and.....died less than a mile down the road. Sometimes it would actually make it a full mile if lucky. It would idle in the driveway for 30 minutes, but as soon as it was under a load it would starve within a mile. I took it back to OhReally?'s, got it replaced under warranty and installed the new one. The truck started and ran, but had a "miss" when under a load. The next day we drove to church, 35 miles away and it made it all the way there, then 5 or 6 miles to our friends' home for Sunday dinner. On the 5 or 6 mile trip back to church in the evening it died twice but started again after a few minutes. When leaving church to go home it started but died before even pulling out of the parking spot. Long story short, it died several more times on the way home before finally curling up its toes for good. I tried to prime the fuel system but it had minimal pressure coming from the purge valve. After doing so the truck did start but died after idling for maybe 10-20 seconds. Looks like I get to take this one back for another one AGAIN.
