Ok, so breif history. 89 s10 4.3 4x4. Recently replaced cat converter and 02 it was bearly running. Bought about 2 years ago, alwasy idled high, occasionally smelled like gas.

After replacing cat. It ran great for about two weeks, then all of a sudden check engine light came on, and it started idleing really rough. Took it to the shop and mechanic noticed that fuel seemed to be dripping out of the injectore as well as spraying. Causing it to run rich, which would have been what would have caused the cat to clog. He suggest that it is the fuel pressure regulator.

Anyways, it seems to be a pretty simple replace, exept in both my shop manuals all it says about the regulator is not to remove the 4 screws because it is under extreme spring tension. So can I replace the diaphram? Any suggestions or hints? Is it pretty straight forward? any ideas? thanks
