My ol' girl, The Big White Pearl (my '79 Ranchero), is leaking fuel from the fuel pump. I'm somewhat mechanically inclined, but still quite a novice when it comes to working on cars. Anyway, I'm gonna give it a whirl and try replacing it myself. (Wish me luck!) It looks like a fairly straightforward process. My biggest question...what is the big difference between the $15 fuel pump at O'Reilly and the $150 Holley fuel pump? There's not a whole lot in between. Just how much of a fuel pump do I really need? Any hints, tips, or tricks would be helpful!
