Question Fuel pressure for an 88 350 ?

Hi there, I have a 88 K5 Blazer with the 5.7 liter V8 and I'm replacing the fuel injectors, But I don't know the fuel pressure should be ? Any help is welcomed !

Hope if anyone here is in Texas, I'm praying for you.

Should be around 13psi for TBI unless your engine is really modified.

TBI is a really simple system, believe it or not. Two injectors, a FBR, return system and stand alone computer for the injectors. Can't get much simpler.

Though, "computer" may not be the best term to use.

Literally just got done rebuilding my throttle body, thought this was a cool video if i wasn't trouble shooting already, probably would have done the adjustable fuel pressure like he did here.
