Recognise the black pumps duffil? We got em from napa, and they didn't work well for us. I think they're more of a pusher than a puller, and for our application they just didn't last. The red ones are stock, and a lot of them didn't last long either, but some got changed out prematurely cause the guys didn't know what the problem was. Now we use the holley red labels and have only lost one, and that was only cause the morons didn't realise there was probably a good reason the fuse blew, and just used a bigger gauge wire till the pump gave out. The holley doesn't care where you put it either, they just flat get it!
Oh yea, this isn't even all my stash! I keep 2 or 3 in the truck at all times!
