well with some quick research, i found a little tag on the fuel pump. 12833.. i looked it up on keystone and it turned out to be a part number for a holley fuel pump.. but no info, so i went on the holley website and looked up the part number i learned its a 80gph pump at 7.5psi of pressure


should i go ahead and get the same pump, or would you guys recomend me to go bigger?

80 gph would probably work okay for you but 7.5 PSI will probably unseat inlet needles and thus rapidly flood the engine. You would have to run a regulator at 7.5psi which cost more and tend to fail from what I have seen.
