ok... thanks again for all the help...

i'm gonna follow the line that goes into the manual primer pump back towards the fuel tank to see if there is a prefilter along there somewheres...

if i have to replace the prefilter, how do i prime it?.. do i just fill it with diesel before i put it on and pump the priming pump afterwards to bleed any air?

do these priming pumps auto-bleed somewhere or do i have to open a bleed valve somewhere to let the air out?
