The '83 EEC-IIV or so still uses high pressure fuel injectors at the throttle body. Should be around 40 PSI or so. Should NOT change with manifold vacuum as they are not subject to manifold vacuum at the tip.

If you are reading 90 you either have a stuck regulator or more likely the fuel line hooked up backwards. I have seen many EFI swaps where the fuel line got on backwards. Remember the regulator goes on the return line.

Low pressure pump is carter P4070 advance carries it in the master brand about $64, high pressure is ES2000 master brand listing is 88 F-250.

You are quoting lbs per hour not pressure 38-40 psi is what you want.
