RE: fouled
The fuel pressure regulator is located under the upper intake plenum. Have a read through the link below and let us know if you have more questions:
Fuel pressure regulator on Blazer 4.3L CPI W engine (incl'd EGR and IAC check/clean)
And as Ryan said above, you have to get a fuel pressure gauge to test the pressure. You should be able to pick one up for $20-$30. Mine is/was an el-cheapo and has lasted me well over 6 years of use on various repairs.

i just went out to check my pressure and i notice that my needle is bent. would that have anything to do with pumping to mych gas in it?

RE: fouled
You mean you bought a fuel pressure gauage and the needle was bent on it when you bought it? What do you mean by 'pumping too much gas in it'? I'm afraid your post is a little confusing.

RE: fouled
The schrader valve stem on the fule lines is bent?? Is it bent to the point of not being able to check fuel pressure??

RE: fouled
yes it is.i tried to get both hands in there but no use. so i called the dealer i have to buy the whole rail. the auto parts stores dont carry it. called a few local junk yards no blazers in the lots. will a schrader valve from a different blazer that isnt 4.3 work?

RE: fouled
You should be able to pull the valve out with a regular tire valve extractor. And yes, the valve from any other similar year GM vehicle should work, but get a few incase you damage the seal.

RE: fouled
so i can change it like changing one on a tire then. do i need to take the schrader out at all.

RE: fouled
The schrader is what you are in need of replacing is it not...? If it is, then yes, you can remove it from a fuel rail just like removing it from a tire.
