    fuel pump pressure for first gen

    hey yall,
    I've got an '83 turbo. i'm looking at the walbro pumps to keep the IP strong, I know it needs to be low pressure but how low? Would 6-8 psi be too high?
    Thanks

    I've been running my pump at around 8-10 psi into the injection pump for a while now. In my experience that much pressure won't be a problem
