.... how are your rebuilds better than one of the economy builds? I believe you when you say they are, but certainly there are corners that are cut to get the cost down to the el cheapo prices, corners your guy doesn't cut or extra steps he takes that make it more worthwhile.
You are correct, and there are corners that can, and are, cut by some others who do pump rebuilds. I would not have as much knowledge of this had it not been for one particular client who purchased a well known internet vendor's rebuild and then forwarded it to me directly for conversion into a Moose Pump. My builder commented to me that the pump was in excellent condition with the exception of what he considered the expected life to be. For example, advance piston wear is extremely common. During a rebuild, part of the proceedure is to insert the advance piston into the bore, and use a light to look for "leakage" around the piston. If any is found, then the bore has to be enlarged and a larger size piston installed. The process of checking for light leakage can vary from builder to builder. My guy likes to spend at least 10 minutes, studying this relationship of parts to ensure the highest precision fit. He has found through experience that if you just stick the piston in, shine the light down there, and look at it, that you will not see any leaks immediately. You have to go into it with the idea that it IS leaking, and then prove through exhaustive searching that it is not. He has spent 7 or 8 minutes looking before seeing the slightest trace of light that confirms that their is in fact a problem. Now, how bad a problem is this? Perhaps not enough for the advance piston to act up now, or this year, but 3 months from now, or 3 years from now, or 30,000 miles from now, that tiny leak may turn into something that starts to effect your fuel economy, power, and performance. So my builder will ensure that the advance piston to bore fit and finish will be good enough to last the full measure of what Stanadyne expected that pump to last when it was designed. This is just one example of one area where taking your time, and trying REALLY HARD to do the absolute best you can is what seperates a Moose product from the others. That's not to say that other builders are not just as good and just as carefull. But what it does say, is that there are some builders out there who are only interested in making sure the pump doesn't come back under warranty. They are not conscerned that 2 years from now you will be coming back to them for another pump. Of course fuel quality has a lot to do with how long your pump will last, regardless of who it is from, and certainly the fuels offered today are not as good as what we started out with, but with proper additives you can certainly get the full measure of service out of any pump. What that measure will be, is determined by who rebuilt it.
