Sorry to have such a lame question, but im hunting for the Fuel Pulsation Dampener, because of a "smell of gas" situation in the engine bay. Everything ive read says its under the Upper Intake Manafold. I *Think* I know what this looks like but id just like to be pointed out to it before I go takeing things a part. I have an 88 Turbo II. I pulled off the Inter Cooler yesterday to take a look for the Dampener but to no avail.

Id rather be lame with the question then have the engine bay catch fire thats for sure.

If any of the vac lines are broken etc while im in there ill replace those as well. Otherwise its got to be left alone, I need to get the car smogged and im afraid of them running it on the smog machine for it to catch fire...

Thanks!

 

the PD is located on the primary fuel rail. On the s4's it has a plastic cap that yellows with age and you usually find the little screw in that plastic cap that has fallen out of the PD. you can also find pics in the FSM(www.iluvmyrx7.com under manuals also www.fc3s.org) and in your haynes/hayes manual.

 

Thanks, I guess I got confused as to where it was located then... or maybe it was for a different model for which I was reading...

 

well the primary fuel rail IS under the upper intake manifold. so your right but its not on the intake itself.

 

while i have a thread going might as well ask a couple more questions...

Shoud I just order the pre-made kit for the Turbo II from hosetechniques.com ? Or just get the right mm hose and order a bundle of it?

Do I get the replacement gaskets for the Injectors from?

and is this the upper intake manafold (see picture below):



Thanks!

 

Is that your car elfking? What kind of throttle cable is that?

 

No sorry its not my car, its the car on the www.hosetechniques.com website when you choose the 2nd gen kit for a Turbo II.

 

Looks to be a stock one to me.
If your talking about the red hose near the throttle cable, it's actually a vacume hose for the cruise control.

 

Taken from the hosetechniques FAQ

"With the Show Kit (containing 70 feet), you can of course replace all your vacuum hose, windshield washer lines and hood hold-up rod, then you can also use the additional hose to "slit 'n' cover" many parts of your engine, such as throttle cable, battery cable, cruise control cable and wiring harness. Usually wherever you have split loom (also called wire loom), you can also use HT SVH. It's a very easy process -- all you have to do is use the HoseTechniques SuperSlitter to slit the appropriate size hose for whatever you want to cover, then place the hose on (turning the slit side down) and tie wrap the hose into place."

Cliffnotes: They use the extra silicon hose from the kit split it and use it as a loom. My throttle cable is cracking in certain places and this sounds like a great idea.

 

So I take it the arrow I drew is the intake manafold ? Otherwise I would have been flamed?

 

I retract my previous statement then! hrmm..

So then why don't they have a shiny red vacume hose going to the cruise control actuator? werid...

 

As to the pulsation dampner, on S4-N/A's, it's located directly behind and slightly below the thermostat housing, at the front of the intake... looks similar to a mushroom cap/top.

 

Ok ive got a couple pictures of what the FPD looks like, so I think I can spot it. What im trying to figure out is the upper intake manafold to take off in order to locate it. (On the Turbo II model from what im understanding is underneith the manafold) So I want to make sure im taking off the right stuff. Above I posted a picture with what I think is the manafold but I wanted to make sure before I go ripping things apart tonight.

Thanks.

 

Yes.

 

They do. Look again.

 

Incorrect.
There were two types of cruise control actuators: the electrical version pictured, and the vacuum version typically found on 86 cars (though it did exist on other years as well).
Since there is no vacuum line for the electrical version (square black plastic cover), then that MUST be a throttle cable.

 

Hrmm interesting.. you learn something new everyday... I just figured they were all vacume operated, but now that I think about that I can see how an electric one might be better for turbo cars..

So that red throttle cable is just a cover then yes? like that black curugated conduit stuff that you put over wiring looms, only red?

 

Yup just red vacuum hose split and pulled over the throttle cable. Looks nice though and hides all the cracks that I bet alot of us have.

 

Answer:
Helps to read the whole thread

Its just extra silicone hosing that someone has split down a side, and then slipped over just as you would with the electrical conduit you describe.

 

Those cracks exist on the majoirty of TII's. The underhood temperatures created by the turbocharger cause the plastic to become brittle and crack apart.
Its usually best to just replace the cable with one from the dealer, as this cracked throttle cable loom can cause a sticky throttle and unneeded gas pedal pressure.

 

Hrmm yeah I guess I missed that little bit..

I wonder if they make it in blue..

 

Super blue and flow blue... take your pic.

Thanks for the advice and info scathcart. I'll probably pick up a new throttle cable and put silicone hose over it when I get a hosetechniques kit.

100USD!!!?
Far out... I might wait for the Aussie dollar to climb a little higher before I buy...

 

Someone was looking into having LOKAR make a braided stainless steel cable, but I have not heard if that ever went through or not.
The stock ones will take several years to harden again.
