hey all i'm doing a cummins swap into an 87 chevy, heres my questioin, a friend of mine has a power steering pump off of a 4bt, he says its a chevy pump that is factory made to bolt onto a cummins, the 4bt came out of some sort of box truck....and is equipped with GM alternator,P/S pump, and transmission......so he wants to trade me the power steering pump that is on my engine out of my 92 dodge for his power steering pump off of his 4bt....he wants to run power brakes and im running hydroboost.....his pump seems like it would be ideal for me because it has a spot for an extra return line which i will need for my hydroboost brakes.....so tell me is this seem like a good deal to you all?....and can i just plug off the oil line going to the pump?.....will it work? thanks for all help....

 

Yeah, that's fine.

You are still gonna need vacuum for the HVAC system though.

 

really? what part of it? the truck is non-ac and it going to stay that way....and the heater controls are cable operated....am i missing something?

thanks a million for the response

 

If it did not have factory A/C you are good to go then.

The systems with A/C need vacuum for the mode doors.

 

ok....yep its non a/c factory....i just figure it will make for a little bit cleaner install and i will help him out so he can run his vaccum boosted brake system....thanks for the help!
