PO175 and gas smell

[454cid]

So I looked......and can't find it. Where is the fuel pressure regulator on a 96 454?

It's on the back of the injector rail. You'll probably have to pull the upper intake manifold off to get to it.

Has no one else got this code, ever? No one knows what it is? I don't have the money to try to replace several parts to figure out what it is.

I just had someone install new injectors (22lb) and I am getting a too rich on both banks now. I think the factory are 19lb. Hoping someone can confirm that. Is it possible the injector you got is the wrong size?
