    got gas?

    i'm currently swapping my old carbed gen 1 for a 01 ls1 in my 87 jimmy,the engine is already in,,sent off for headers,and wiring harness and ecu have been sent off to be modified,,alot of the hard and most exspensive stuff is out of the way,,but now i've made to the fuel system,,and was wondering
    which fuel pump/tank/fuel lines i need to run on that engine,,,ive heard too many people telling i need to do this and do that,,external or internal,,or one out of this model works,,or my tank won't work. really need a final say on what to use,,,i've been told many things,,or just pointed in the right direction



    thanks

    The LS1 will want 58 p.s.i. with the stock injectors to run correctly.
