    where at?

    leave the stock setup.

    I assume you're doing a carb swap? Buy this regulator :

    then route the lines in the engine bay using common sense.

    Need some more info on the motor setup, and then we can give you some better (non-smartass) help

    The factory runs fuel lines over the transmission

    Just run it up the left frame rail, into tthe engine bay, across the fire wall, to the pump or carb.......like superbee said

    its just a 4.3 to stock 350 v8 swap with a five speed trans i used engine mounts i ordered from summit as for the fuel line as of right now the fuel line is got a bunch of sections cut out of it and rubber hose here and there so i want to get all back like it needs to be.but like i said everone has been flipping out when i said i was going to go metal line from the tank to filter then metal to the pump but go over the trans (everyone is afraid of the driveshaft snapping or something) ad i figured id at least get some other ideas before i went to work on it today

    350 swap.....we got that......carb, trottle body, MPFI???

    And the stock fuel lines are metal with sections of rubber hose for flexing

    If you go carb or TB you can leave your entire fuel system how it is stock with an aftermarket fuel pressure regulator

    MPFI needs a high pressure fuel pump and the rubber sections of line need to be replaced with higher pressure fuel line

    its gota carb

    But here's the problem the guy I had working on it took the pump out of the tank and ran a bunch of metal line and rubber line put together with hose clamps (none of which were tight noire secure) so now I'm trying to go back and take most of the rubber sections back out and secure everything.but on top of all of that when he did what he did he ran it in the way of the exhaust and right up next to the header

    And his reasoning behind the pump idea was that a electric pump put out to much fuel pressure for the carb so he pulled the pump out and put a mechanical pump on the engine.

    And trust me this is only the first of his dumb mistakes that I have found and had to fix

    not for nothing...hope i dont get anybody mad... i once did a 305 swap for this guy who wanted one in his 89 s-10 blazer...i found out from my buddy that he fancied himself as a "tinkerer" and then liked to blame the problems he caused on whoever worked on his car last.. so i did the same thing, i swapped the fuel pickup from a blazer to a 79 buick century pickup (they pretty much all fit, the opening in the top of the tank is pretty much universal). i did however run all new metal line from the tank to the passenger side frame rail up front (and properly secured it with metal clamps-the ones that have the rubber insulators in them to avoid chafing and breaking the line). did the rest of the swap and have had no problems with it still... it's just that some folks work on other peoples cars and just dont care..that's where the problems come in.. but do remember on a blazer fuel pump pressure is around 57-65 psi if im right(dont quote me) which is way too high for a carbed motor( they usually will rum with 7 to 9 psi) so in a way he was right, just went the wrong way about handling the problem..
