Location: NorCal | Has anybody used a later pump with higher pressure on a FL? Has the higher pressure caused any problems?
The pump on my '57 is rated at 750-800 psi and the pump I want to use is rated at 950-1000 psi. Don't want to damage the steering box. |

Location: Southern Sweden - Sturkö island | Hypothetically, the piston seals will withstand a higher pressure, however, I'm not sure if the reaction ring washers (thin shim) would like a higher pressure.
The newer pump should have a releif valve (I guess), so prehaps it would be possible to adjust it to a lower pressure? |

Location: SE Arizona | For what it's worth 25 years ago I ran a Saginaw pump on my 57 Dodge (with a 58 and up PS gear) with no issues. If the pump your planning on using is a Saginaw you can now buy replacement relief valves that will reduce the Saginaw pumps down to the 800 PSI (which is what is recommended for the Mustang II Racks used on a of of hot rods). |
