Hey guys I searched this topic and came up dry.

Put a used mp112 on a 01 5.3
Fired it quick the other day and have a lot of raw gas coming out the exhaust.

 

Gotta give me more than that.

So just the blower swap only?

No injectors, no fuel pump swap?

What's the wideband reading, overly rich?

You sure it's not condensation?

 

42 lb injectors from the original kit (cleaned and tested)
New inline pump (that came with the magnuson kit) from Brian at SCOL
New return style fuel manifold from SCOL as the kit came from a returnless truck

For sure not condensation definitely raw gas, thought I was going to burn down my garage.

 

Check for leaking injectors and get it tuned.

 

If it hasn't been tuned for the 42's, that is likely your problem.

Found an injector stuck open. Got it cleaned and tested just waiting for a tune now.
Thanks guys.

 

My best guess was the fuel rail had something in it (came from the guys storage unit) and got stuck in the injector.
