87 silverado engine change
 

I replaced my 350 tbi with a carburated 305. what do I have to change on the fuel system to adapt it to the carburator?

Wow..never seen anyone revert back to carb..

The pressure will be too high...13 psi will probably just blast past the needle valve.

i would imagine gut the fuel pump. and cut down on the computer and youll be alright

im doin the same with my 1989 , but i have a 350 ... i was told just to put the mechanical pump on the motor and it will regulate it for you , but another friend told me that there would stillbe probleums with the intank pump ... so i guess youll either have to buy a regulator or remove the pump and just use the mechanical ...ill post my results after i get done with my swap this weekend ...
