91 lo3 problem

I have no top end, it hesitates on hard acceleration. I put a new fuel pump in about 2 weeks ago with new filter, it ran great for about 1 week. I cut the panel above the fuel pump so i would not have to drop tank and i repaired fuel lines with clamps & rubber hoses. If it idles well but hesitates upon acceleration should it be a fuel problem?

Re: 91 lo3 problem

Did you recheck all your clamps/connections? what fuel pressure are you running?

Re: 91 lo3 problem

I did check the clamps. The main fuel line is a little tweaked The rubber hose I used). I think I used 5/16 hose on all lines but my neighbor thinks I need 3/8 on the main line does anybody know what size line it is?
