When I received my 1961 GMC 4wd Suburban w/305 V6 it would starve for gas on a long climb, it has an electric pump mounted on the frame, if I switched it on the engine would run fine. The only pump I could get was an Airtex, this cured the problem for about 100 miles then the same thing. I put another new Airtex and it worked for a couple of weeks then the same problem. From what I can tell this is a common problem with Airtex pumps. It seems the best pumps for the V6 is a Carter if you can find one. I don't put a lot of miles on the Suburban, so this took place over a couple of years. I guess this is why a lot of folks run an electric pump also. I have an electric pump on my 1966 GMC 3/4T pick up also. Hope this helps someone out.
