Just received my kit today. I have the non-dampened version. Although the kit comes with an email with install directions, the images in the email are difficult to reference b/c they are taken so close up. I'm not positive which way the lines go and which goes on top.

The kit has two lines. One with a dampener and bracket and one that's just a plain line. Is it correct to say that the plain line goes on top of the dampened line? I see 3 barbs on the firewall and fuel rail. Looks like this kit installs on the top and bottom barbs, leaving the middle line alone.

?

Trace the existing lines. On the firewall side, there's a top line, a middle line and the bottom line. Leave the middle one alone (which I believe is blue and is for the evap canister). Top and bottom needs to be disconnected.

On the manifold side, there's a top and bottom port.

Basically top manifold port needs to be connected to top firewall port ( aka feed line or the plain line)

Bottom manifold port needs to be connected to bottom firewall port ( return line that has the fuel pressure regulator, not damper ).

What kit you get? Take pics of the regulator.

Thanks for the detailed explanation. That makes perfect sense. I purchased the IAP kit. Apologies for calling the regulator a damper. My only other question is how to know which way the line with the regulator goes. The instructions says to use the longer side towards the firewall, but both ends look similar. IAP is calling this line with the regulator the "return" line.

I'll get a pic of what I have. Thanks!

The hose that's attached to the BODY (left side) of the of fuel regulator is hooked up to the return line on the manifold (bottom port). The one on the right side is hooked up to the firewall return port (bottom port on the firewall, below the blue line).

You also need to attach the pressure source to the nipple of the pressure regulator (top).

Using the pics provided at the beginning of this thread, I was able to perform this install. Needed the fuel stumble mod per Eric @ TP's request. No leaks or complaints and it looks just like a quality OEM piece. Thanks Funks.

Don't really like the way IA did theirs - it doesn't bolt on to the OEM bracket and uses a rubber/metal clamp to secure the FPR assembly to another hose.

Doesn't come with a new silicone hose for the pressure source, nor corbin clamps to keep the pressure source hose secure. I guess a longer silicone hose ain't needed as the regulator is closer to the manifold ports on their setup (so the OEM pressure source hose reaches).

Works the same way though.

Hmm. That part of the install isn't even mentioned in the directions. I was wondering that that nipple was for, though.

I did injectors, tgv deletes, phenolic spacers and this FPR mod this weekend, I'll post some pics tomorrow if I have time. The install is a lot easier than the pics make it out to be. Just poke around for a few minutes and you'll see where everything goes. Two things, first the fuel lines are pieces of crap to pull out, I bought a tool to take them off, didn't work, I did the two zip tie trick, didn't work, finally I ground down two large cotter pins flat and it worked well. With that said you do not have to remove the lines coming out of the firewall. Just take them off at the FPR and buffer and plug the new FPR and buffer in the hoses, clamp them down and you're done (unless you're not using a buffer than God bless you). Also,you can use the flange bolt , spacer and nutt, as per the shopping list on the first page, just bend the bracket to line it up. Like I said, I'll post pic tomorrow.

See my post #57 for a ghetto solution to disconnecting the fuel lines that works amazingly well.
