How do you install a fuel pump for a 1984 Chevy C10 truck?

peice of pie, loosen fuel line at carb- remove fuel lines from pump as well as 2 mounting bolts(sealant applied to threads)-swap pumps.lubricate pivot pin in repl. pump with heavy grease,watch not to let pushrod fall out of block as lever from new pump needs to be aligned underneath it. secure new pump,hook up and tighten lines and you are good to go- mechanical fuel pumps were a drean to install. heres a tip- use o.e.m. pump as they are better quality than jobbers,they have a flow back valve in return line that adds life to pump diaphragm nad be sure to pack the pivot pin area as oil pressure is too low to provide adequate lubrication and will develop a knock in that area.
