Message: [QUOTE="Mr.BigOil, post: 1033561, member: 16235"] Well, I been lurking over here for a little while. I don't quite understand your question/comment on the two mounting bolts being an issue. Those bolts are custom ordered and are a 12.9 grade 8mm bolt. Very strong. Yes, timing cover threads have known to strip out. A couple reasons: removing and reinstalling pumps/or a pump, over and over and over again and again... Over torquing the mounting bolts. Cross threading the mounting bolts. Using Loc-Tite on the mounting bolts. But pump weight has no bearing on the bolts. You see that thick aluminum snout on the front of the pump body(1 1/2 inch thick). That's a static fit design. There are hundreds of inline duals out there, with well over 150k on the system. If anyone is really worried, hit up fasten all for some thread inserts. I think Riffraff Diesel sells the kit as well. Personally, I don't repair threads unless they are damaged, but that's just me apparently. As for the Stealth issues: I have seen a few. A broken spring can cause damage, as said above. Once steel gets between the brass revolver, it will only take seconds to damage the smooth surface. Once it's no longer smooth, you will lose pump efficiency. Most of the damaged pumps are actually much worse then "a broken spring". It's usually several springs. I won't go into the reasons why they are breaking. As for a Billet body, that won't make it any more reliable. There's plenty of room in there and if the body was the issue, we would see cracked/broken body's. We're not. Fact of the matter is, dual pumps are and always will be king(what ever brand you choose, as I really don't care). The amount of volume is crazy and gives you throttle response that no single will touch. Also, if guys choose a 238/???, any decent single pump will supply those well. If the 17 won't, then have it rebuilt to: which ever company you choose. [/QUOTE]
