It shouldn’t if you cap where the tube used to run into the TBI and where it runs to the gas tank. This will avoid a vacuum leak and your truck smelling like gas.

looking for feed back on roller tip rockers, 1.6 ratio self aligning for a 95 tbi 5.7 with 70k miles on it.

What brand dizzy did you buy? I bought a Spectra Premium in which less than 3,000 miles my engine started surging and the tach would jump up over 4K and back again.

I'm seeing more and more folks finding this was their issue. These ICMs don't last very long, especially cheap replacements.
The crank bolt is stripped just barely.Which bolt? The engine is SAE NC and most of the accessories are metric.
