Can anyone tell me what all I need to consider if I am contemplating replacing
the fuel injection system with a carburetor on my '84 Vanagon?

    I have a manifold and carburetor that I used on a 1967 Microbus (dual
ported heads).  Can I use that?  If so, what psi fuel pump should I replace
the FI fuel pump with?  Also, are there any down sides to this plan?

Thanks.
