[QUOTE="Big Bore, post: 28499, member: 760"] OBS is a mechanical lift pump in the valley with tiny 1/8 lines going to back of heads and a regulated return through the fuel bowl/filter housing. SD is electric pump on the frame and dead heads to the heads. Which is why DI does so well selling regulated returns. If you scrap everything it doesn't matter. Most guys have scrapped the entire fuel system on either models. Mine is getting ready to lose the last vestiges of the stock system, the fuel bowl/filter housing. [/QUOTE]
