Hi, could anyone tell me what the fuel pressure should be for an 85 T-type? I'm having major detonation problems and a serios lack of power. I'm getting 30psi at idle and 38 with the vacuum line off. Any help would be greatly appreciated!:dunno:
Set it to what ever it likes. If you have a 255 lph pump I would set it at 42psi, as mentioned above. If you have a smaller pump you might have to go to 50 psi. Best is to get a scan tool and figure out if its a fuel pressure problem or and octane problem.
