Will that one screw right in to the number five or just lay it over there. The car does motor pretty good but like you said I need to button stuff up
it will not thread into the intake unless the intake has bedn drilled and tapped for it. You will need to do a search as its been too many years since i've done an explorer swap
Agreed, some have found a way to extend this and put it into the intake box. I believe Jrichter has a write up on this.
 
ok......

The intake is from a Ford Explorer and is similar to a Cobra or GT40. Your throttle body looks stock, and some type of ghetto rigged EGR. Your injectors look like lucas aftermarkets- maybe 24lbers? You also have an aftermarket Mass Air Meter. which I assume is matched to the injectors- cant tell as the writing is off. You have an aftermarket fuel pressure regulator and fuel pressure gauge... You can verify what size injectors you have by opening up the FMU carefully and seeing what size the disc is.

19#/Hr.- 12:1- 2.7215"

24#/Hr.- 8:1 -2.2220"

30#/Hr.- 6:1 -1.8525"

WIthout knowing if you have a chip or a tune, the stock fuel pressure should be 39 with the vacuum line removed and plugged.
if I open it what do I expect is fuel going to squirt out and is it easy to put back together.thanks
