I've done that job before. Being able to see it from the engine compartment, you'd think it would be easier to replace than it is!

 

I know right. Doesn't help that it's under 15°F here in the garage. Luckily there's a propane heater I can use. Haha.

 

Just finished repairing my stuck electric drivers seat. (2001 ZR) Had to remove the seat and replace the cable between the two gear boxes. (Among other things)...

 

Hey does anyone know if I upgrade my fuel pump, can I force more fuel through the stock poppets on my 1998 4.3l

 

This question should be posted elsewhere.

 

I’m posting it on forums about Chevy blazers also an upgrade fuel pump will be install soon also don’t reply if you don’t have an answer.

 

This is not the correct thread to post this question. Start a new thread in the sub-forum for the year of your Blazer. E.g., for a second gen Blazer https://blazerforum.com/forum/2nd-ge...-2005-tech-41/

 

Your closed loop fuel management system will use the O2 sensors to monitor oxygen content in the exhaust and continually modify the fuel injector pulse width to maintain minimum emissions by maintaining the air fuel mixture as close to 14:1 or stoichiometry as possible. Your engine computer will fight any attempt to increase fuel injection volume unless you are tuning for performance and increase air volume or volumetric efficiency. As far as the fuel pump and rail pressure goes that is regulated by the intake plenum regulator not the fuel pump output capability. Your question might apply if you were building a higher horsepower motor with say a turbo or blower and needed more fuel volume and then you would need new computer maps, etc.

Welcome to the forum but watch the insults or you won't get the benefit of the knowledge here. I could use the same attitude regarding not providing enough detail in the question to be able to give a proper answer.
