Hmm is it normal that I can smell I little of gas when I drive? It's not a strong smell, but it's noticeable.Thanks!

If you're smelling gas there's a good chance it could be the pulsation damper which resides in the middle of your intake. Raise the hood and check to see if it's leaking. If you see gas do not drive the car. There are a lot of guys around here who've had their car burn because of this problem!

Could be the Pulsator Dampener. Ya especially since it is an 88. Might wanna just change it to be safe. You can upgrade to the 89+ but think you need, mmm..the fuel rail as well? Someone help me out here.

I think you should pressurize your fuel rails and get a flashlite and mirror and do a thorough search for the source of the leak. You probably know it, but there is a connector near the r/h strut tower that can be jumpered with a piece of wire. When you do that with the key in the on position the fuel rails are pressurized and you should hear a hissing sound of the regulator bypassing the excess pressure. You've had the dynamic chamber off before, so take it off so you can see everything better. If you don't see anything after a thourough search its probably something else. Are you charcoal canisters connected to their pipes. I left the canister out for some period of time and every time i had the vent open on the Logicon, I could smell fuel from the vapors from the open pipes that go to the canister. Just a couple of things you might try out. I'd sure check out the fuel rails while pressurized or carry a fire extinguisher with me. Or, if you have good insurance........

I used to get a fuel smell from a disconnected vacuum line behind the IC.

I had that for months and couldn't find it. Until one day I was working on something else and found a little fuel line underneith the throttle body. About 3 inches long and a pain in the *** to get to with out removing the TB. that was it. It only cost me the new clamps because the guys at the parts stor like me and gave me the new fuel line free. Just ask them if they have any scrap that is at least "this" long. ( when you say "this" hold up your old line"

I also used to have this problem...I changed the fuel filter and there was no more smell.(10 minute job)

With all the above posts in mind, do check the PD. Even if you replaced an 86-88 one earlier, they still go bad. The best ones to get are the 89-91 (Series 5) PD's. They go bad as well but not as soon as the series 4 ones. Everything stops working after so long! Get the Series 5 PD new or used, but do it. Don't forget/lose the little washer under your PD, you'll need that and you have to get the bolts from the Series 5 PD since the left mounting bolt on the Series 4 is longer. You won't have to change out the secondary rail. Stay away from putting a bolt or other modification in the end of the PD. Its a hassle! By all means, don't glue the little screw into the end of the PD on the Series 4, no matter how many good luck stories you read about it. They were NOT meant to be JB welded!
For fuel line, make sure you get the stuff for fuel injection systems, not the ordinary stuff. It can't handle the higher pressures. The FI hose has reinforced walls.
