Hope this is big enough to view

SOURCE: fuel pressure regulator

How do you know that it is the regulator?
these 4.3 motors had a lot of trouble from 93 to 98, I know I had 2 of them.
What happened to mine was that the intake kept getting very carboned up. After I would clean it, the truck would run fine for about 5 or 6 months, then same thing.
Theres actually a class action lawsuit about this that I believe has been settled, you may have recourse if you bought it through a dealer. Good luck.You'll need it.

the fuel pressure regulator is located inside the intake. you have to remove the upper intake to access the regulator. the black plastic intake is what you need to remove.
