    in- tank fuel pump choices

    Trying to decide between walbro 255 for $99.00, edelbrock 3581 for $102.00 or delco ep 381 for $50.00. All three are complete kits. I would opt for the delco, (cheap),but thought I'd ask before pulling the trigger and making a mistake. Thanks for your input!

    what are your power goals? If going performance then skip on the Delco pump and go for the walbro, it's designed to support more HP.

    Why not skip to the 340 if you are going with the walbro? I think supercharger connection sells them for the same price.

    I'm planning on about 350 hp,just a reliable dd and maybe some road trips. If the walbro will be more reliable I'll go with that. Also gives me the option to make more hp down the road if I choose. Thanks.

    If you are ready to settle at 350 you'll be fine with a stocker. At least I am anyway, never ever have I seen my pressure drop below 60 psi
