Here's the thing, and I have no problem with someone who wants to buy a cheap rebuild, but know this. You DO get what you pay for. A large component of the price is the labor spent on rebuilding it. Let's face it, we all know how businesses work. You can make your money on volume, or you can make your money on reputation. If your working the volume angle, like Walmart, Pensecola, McDonalds, or what have you, your going for the lowest price. That means getting the lowest price from your suppliers, and paying the cheapest you can for labor. It also means skipping time consuming things, like inspections, quality analysis, retrofitting, updates, basically anything that is optional to producing the product at the minimum acceptable level. That level, as far as IP's are concerned, is that it makes your truck run, and doesn't leak. However, that doesn't mean it will make your truck run WELL, get the best power and economy, and do it for longer than what the warranty period covers. Here at Moose labs, my assistant Breaker (Ok... ok... I really don't have an assistant named Breaker, but the whole muppet labs thing was just sounding too funny!
) has taken many pumps sent in for Mooseification, and the thing we find consistent with the lower cost rebuilds is this. Worn parts, old seals, faulty solenoids, dirt, rust and scale, and improper assembly. Typically, yes the pump MIGHT run OK. For a year or so. But these guys do not rebuild the advance mechanisms, and they do not clean the insides until they are spotless, and they do not replace the little stuff that can make or break a pump. So if you choose to save $200 or $300 bucks, just know that your not really saving anything, because you will be spending more money again very soon. In fact, you may buy 3 pumps in the time that one high quality pump would have lasted. There is no free ride people! You can pay now or pay later, but you will pay.
