Some say its on the fuel rail and others say its on the fuel pump. I have supplied a pic of where I think it is. Is this it?

this is only a connection not a regulator it is usually referred to as a quick connect

I'm doing a swap right now, 96 motor and ac15 into a 92 body, noticed the difference in the fuel rail right away and an extra plug on the 92's throttle body. Should be fine running the rail regulated setup and 92 file system right?

an OBD2 equipped '96 has a different fuel return system & regulator to earlier sytems

the fuel pressures are different. Should be doable, if you swap only the right parts

Feel better now?

Accurate information is accurate. Inaccurate information should be corrected.

light0070702,
Please post the link to the part as I have been searching for days.
Actually it looks almost the same as the one on the fuel rail.
I just don't know which one will work.

Thanks,
Joe

this thread calls out the 96 fuel pressure regulator part num...which is the same 91-96

the thread states the reg will put out 49psi for '96 vs 39 psi pre '96, due to the vacuum line not being connected

The pressure regulator is inside the fuel tank with the pump on my 1996 classic and the rails looks like that

I do not have one on mine....

is it normal?
Thank you for the enlightenment...

Ok so i ran into this problem a few months a go and even the repair manuel didnt mention it. I found out via a youtube video where someone was talking about another issue and said it as a quick side note. So the 96 was the last one to have it as part of the fuel pump assembly. IF you are planning to change that part or the fuel pump DONT WASTE YOUR TIME AND MONEY. buy the WHOLE assembly. It come with both parts new. As well if the assembly in the gas tank is flaky as in you can see flakes on the metal this can cause bad contact for the electrical components. Iv already been through that

Ooohhh yeah the hose thing I saw that on mine. Its a bypass they do. I think its for when the ac dosent work or aomething like that.
