Andrew (spinz71) uses his truck for a daily driver and the kit has been on at least 2 years. I dont really think its out of the ordinary to replace the pump after the use it has seen.
Not sure why they wont call you back. Let me know if I can help.

 

You joke now but last weekend Henry and I were really close to making a deal for his 112. I think you'll remember that last year I was talking with you about a compound system before everything hit the fan with my truck and Henry gave me a great deal on his SC that I almost couldn't pass up but the timing for me wasn't right seeing that I just got my truck back and didn't want to tear into it again.
But by the end of the year after I get some miles on my truck and things settle down I'm still interested in making a compound system so...we'll see!

 

PM sent...thanks!
