Getting my big block Longhorn running again

[kwmech]

Having some small issues, truck been sitting for just about 6 years now. Got new batteries in it and the oil pressure up. I pulled out the 396 years ago and put in a TBI 454, and as a result am running a frame rail pump. Needs to be changed, but before I was just using the NAPA pump rated at 15psi (I think). Brand name quality pumps available??? Still have to clean out the tank and get better fuel in it and the injectors seem to be gummed up also. The new fuels really suck.

So recommendations on a pump and where to get quality fuel injectors, been through all the ads on the internet with Ebay and amazon. Never actually taken a TBI injector apart--is that possible so I can clean them out??
