ok im getting ready to put the upper plenum and fuel injector block back on an L23 3.4L MPFI or SFI or whatever one it is and i need to know which way i should go about this.


should i reattach the block to the upper plenum

or should i wait to reattach it until after i set it all on the LIM and bolt the upper plenum down and then push the injectors and block down and reattach it to the upper plenum ?

this is on the car BTW and its a 4th gen and it wouldnt really be an issue if it were in a 3rd gen due to lots of room on the third gens...


so...

whats gonna be the best way here?

also i removed the hard lines from the injector block.

also, should i disconnect the quick line fittings on the fule tubes and install the lines back onto the block before installing the upper plenum and block back onto the engine?

thanks for anything
