I'm on my 3rd Walbro. I bought the original kit from Glacier Diesel. 1st pump lasted 3. 5 years, 2nd lasted 1. 5 years, 3rd lasted less than 10 minutes. They appear to be going downhill. Depending on how I get treated under warranty, I'm thinking of going back to stock filter mounted pump. If I can't count on the Walbro, what's the difference? I removed the stock pump because I was afraid of being stranded on the road. I've been stuck twice in one week with the walbro's.
