Im trying to do the master pump deal and just switch out the pick up hose..Im pretty sure I got a 4.0 sfi but there was a question about the vin number.. and the pump pressure being 33-38 Any help appreciated Thanks all

 

It will say right on the intake plenum what engine you have. The 3.9 and the 4.0 are the same engine, the only real difference is the EVAP system. Depending on your EVAP will depend on the fuel pump.
You might need to replace the fuel line.
As for the pump PSI, I am pretty sure that you are right on par with what you have.

 

Do I have to drop the tank to replace lines??

 

I do not know if you need to drop the fuel tank or not.
You might beable to put it all together and then seal it somehow so that it no longer leaks.
I do not know without being there how bad it is. But if the fuel line is completly rusted you will have to replace it. I do not know if you can splice it or not.
