return line for EFI conversion
The TBI system operates on 13+-psi other than the 94-95 454 TBI which doubled the pressure and used smaller injectors for a little better atomization of the fuel.
IIRC that regulator is about 35psi.
The TBI has the regualtor built into the return side of the injectors in the throttle body.
"IF" someone was going to try and shortcut the install by not using a full return then the ford filter would be a better choice.
But...Having personally tried many of the shortcuts posted on the web over the last 10+ yrs for an EFI install, I can tell you that the chances of a vapor lock are greatly increased by not returning the unused fuel and vapor to the tank where the vented fuel cap can release it.
Here is the ford filter.Part Number: FF871DL
Alternate Part Number: FF871
But I don't recommend running without a return.
