[QUOTE="Yaadman_GT, post: 11511811, member: 45269"] I can tell you what Aeromotive is gonna say about the 340s. I have used quite a few of their EFI products and electronics and I also have a pretty good rapport with Brett in the Tech/Sales dept. For a comparison, I ran 3 x Wally GSS pumps for ~2500miles on E85 and the same filter element in a Fore F10 Filter. I had all three pumps running at the same time, all the time. There was nothing wrong with them, I just wanted to try the Aeromotive 340s and see what they were about......been downhill since then. When I swapped out to the 340s, I had the FAST XFI trigger one pump on start-up and the other two pumps were triggered off a MAP signal when it sees 9psi. The first time a pump went out, they wanted to say that it was a clogged/not free flowing filter and that was increasing the line press before the filter and that ran the brushes out of the pumps. I actually dropped my tank and pulled the fuel system out and sent it to Aeromotive for flow testing and fro them to check press drops, etc. So I sent them my Fore Precision Triple Hat Return Style (this was the one with the 3 x outlet ports and 1 x return port, the Fore Triple Y-Block, F10 10 micron filter and all the fuel lines. Brett and I kept in contact through the whole evaluation and the verdict was that the fuel system flow was excellent. No pressure drops, the flow out of each pump was just about even out of the hat and out of the Y-Block. They did say that the F10 filter element was not flowing optimally and that the it wouldnt help to get a bigger housing. I also picked up one of their 7" filter housings. They sent me 2 x brand new pumps (the one that burned out and one of the other ones because it was showing signs of brush wear) and they also recommended that I get an inline fuel press gauge before the filter and watch it after a few hundred miles and see if there is a press increase and that would be a good indicator that the filter element was getting clogged slowly. Well, the next pump went out after about the same number of miles (600ish) and the pressure before the filter was ~48psi. NOTE - My base FP was set to 45psi. I dont know whats up with these pumps, but I cant figure it out and Aeromotive cant either. I've checked the filter elements and the look fine, flow fine. I've dropped the tank and checked inside and there is no debris, varnish buildup, etc. Ever since I made the switch to Ethanol, I've run Sta-Bil E85 Treatment and I've also used the Lucas E85 Treatment, both with great success. My conclusion is that it has something to do with the parts inside the pump. I dont think I've ever heard of a Wally going out in any fuel whatsoever. All these new off brand pumps seem to be going out left and right. Thoughts anyone? [/QUOTE]
