If you are running the fuel injection....absolutely not. No mechanical pump will provide the fuel pressure needed to run it. I don't even know if the 93 still has the mechanical fuel pump mount. Even if it did, the camshaft wouldn't have the fuel pump eccentric to run the pump.
NO, it has only one fuel pump, and it is mechanical.
The 1974 Chevy truck has a mechanical fuel pump with a built in pressure regulator.
If your Chevy trailblazer 2004 gauges are not working, check your fuel pump.
Yes, It is a mechanical fuel injection system with an injector pump to pump fuel to the injectors.
None that I know of.
The mechanical fuel pump regulates the fuel pressure. This truck is not fuel injected. It has a carburetor.
The fuel pump may stop working when you hit the ignition due to the mechanical failure.
It will not run and will appear to be out of fuel.
on the front corner of the block (mechanical pump)
Yes, make sure it has the pin where the mechanical pump goes.
The biggest line goes to the carb.
