I replaced mine on my 90 GMC Sierra. It is spring loaded so just be careful removing the old one.
Flooding can also be a bad temp sensor (in the intake near the tstat housing). When the sensor goes bad, it tells the ECM that the engine temp is much colder than it really is and the ECM gives it too much fuel.
Also note that the if the injectors are leaking (it drips while running), the injectors may need to be replaced.
