Fuel System Replacement
About 4 years ago I had my fuel pressure regulator in my '95 blazer ls replaced. well, now its having the same problems. So I took off the plenum to have a look and the poppet nozzles are all messed up, there was no gasket and much more was wrong. So now I am thinking of just replacing the entire fuel injection system from the filter on up. What should I do? I cannot find anybody who sells the entire CMFI system. Where could I find one?

RE: Fuel System Replacement
Do a websearch for a company called LMC, or Late Model Chevy Trucks.
They sell jsut about every part for our trucks.
Once you see the price of the upper and lower intake, you might change your mind.
Good luck and keep us posted on what you do.

Check with your local GM dealer. There is a new direct replacement spider that upgrades the poppet valve system on CMFI/SMFI systems. Since my old computer died I don't have access to the information that i found. But you may find it on this forum by doing a search. I have discussed this upgrade a couple of times and i believe that i posted the text of some of the service bulletin describing the upgrade.

I would also recommend taking a look at LMC. I do not think you mean to replace the fuel lines as well, but replacing the spider, nut kit and fuel filter are straight forward installs.
