Ok so I have a 1989 crx (DX) and the motor got hydrolocked (dont ask) so I picked up a 91 si motor complete swap It's all put in there but before I go and try and start her up I am going to be droping the fuel tank for cleaning because its been sleeping for a good year n a half.

Now my question is that because im going from a DX (carburated) to Si (fuel injected) I was searching and I heard that you should change the fuel system to accomidate the pressure of the fuel injection. So do you think I should at least change out the fuel pump, gas tank/and/or fuel lines or should I just clean it and put the dx one back in?

Any advice is welcome even if you think my question is stupid
