thats the fuel pressure regulator

Can I drive it home with the vacuum line disconnected?

just don't go into boost.

All that thing does is restrict your engine from getting all the fuel it needs.. I'd just remove it.

ruff spelling and grammar

English isn't his first language. How is your spelling and grammar in Spanish? Hopefully it is impeccable and you can offer your thoughtful assistance in his native tongue.

And I am supposed to know this, how?

If you view his profile you'd find..






























That he resides in the United States. Criticism is probably warranted.

Spanish first and last name coupled with the irregularities. If it was Sergei Andropov, Ahmed Assan, Horst Vanderbruke, or Ude Eko and his English was poor I would likewise give him a pass. Not so much if his screen name was driftmissle69.

I'm from California, there are PLENTY of hispanics named Luis that are literate. So a name means nothing to me.

Shit guys does it really matter if his English isnt perfect. There are plenty of people that like cars , live in the US, and have English as a secondary language. How many other languages do you know? Let's see you post in Spanish and see how bad it is. But giving someone a hard time because they legitimately dont know the proper grammer is petty.

can we move on? I really dont care that much. Id rather not have my inbox filled with useless banter.

FTFY

That's it.
I'll start posting in Turkish from this point on.

Pot, kettle? :dunno:

Well played haha:likecat:
