I read the archived thread about pulsation dampers, and I saw that a lot of you guys replaced the dampers with banjo bolts. It's been a few years since that thread, and I just wanted to know how that's worked for you.

Also, i saw a few guys just use a hose to route the fuel to outside the engine bay for when the damper breaks. Has it broken yet? Did the hose work?

Just wondering, because a lot of those "My Car Burst into Flame" stories were with '87 Turbo II's..which I have. I'd like to keep my car uncooked.

 

go with the s5 fuel rails, those don't have the same style PDs.

 

Well im looking for a temporary fix until summer when i can rebuild my engine. Then I'll be switching to an S5 primary fuel rail.

 

S5 dampers can fail just like the S4's. Why would you want to rig up a temporary fix on something that could very well cause your car to burn to the ground? Get a new FPD or banjo bolt and fix the problem right. There is too much misleading information on this forum, go here for the truth-> http://www.fc3spro.com/TECH/FAQ/pd.html

^^^^^^^ Word.

Do it right. I am going with the Marren FPD, just my preference.

 

Those are still prone to failure, just not as often.

 

so youd suggest what, going to a banjo bolt? Ive heard of people removing the PD and going with a banjo bolt

 

You could go banjo bolt, or you could do the Parallel fuel mod and run an Aftermarket FPR. ITs all in how much you would like to spend, and how much work you want to do.

Some people will argue against the Banjo bolt mod, but whats the hand off? Uneven fuel delivery versus a burned down car? I think the answer is obvious.

 

Is there a mileage rating on how often you are supposed to replace the pulsation damper?

 

I am unaware of one..

 

There is not a factory recommendation for dampener replacement, however I recommend every 10 years or 100K miles (which ever comes first).

 

i completely forgot about the pulsation dampner. i bet mine has never been chenged. thanks for the friendly reminder!! no should i go banjo bolt or the PD???.....

 

I like teh parallel fuel mod, but idk of anyone who has done it. If anyone has it please lemme know how its working for you, and some details if you got 'em .

 

Alot of us have done it, do a search for the Parallel Fuel Mod. I have it on my car also.

 

I am doing it right now....

This is a back shot, but you can see the AN fittings. After I get a bit more, I wil take a better shot.


Look at this thread to get ideas.

^^that pic. is teh sex!! i take it you got the motor rebuilt?

 

YearsOfDecay has a pretty good pic in that thread. Although it looks like his isn't a parallel setup.



But be aware, if you plan to go all stainless braided lines and AN fittings, things can get pricey fast. Here's some parts I was looking at getting. This doesn't include the pressure gauge but does include a new fuel filter.

• Aeromotive A1000-6 Injected Bypass Regulator, 30-70 psi, $135
• 3 Male to Male couplers for FPR (-6 AN), $42
• Earls Performance in-line fuel filter, $28
• Y-Fitting (male -6 AN), $30
• 12 hose end fittings (female -6 AN), $60
• 2 90 degree couplers (-6 AN male to -6 AN female), $15
• 2 fuel rail fittings (-6 AN male to 12mm x 1.5 male), $10
• 2 fuel rail fittings (-6 AN male to 14mm x 1.5 male), $10
• 10 ft stainless steel braided hose, $40

About $370?

 

Thanks !!!! Yes I did get the motor rebuilt.!

 

No rust on your exhaust manifold? Did you paint it?

 

No, I had it sand blasted at Rotaryshack.com. I bought a Hybrid Turbo from Robert, and he blasted it for me. I would like to get it ceramic coated though.

My pulsation dampener failed at less then 50K miles on itacording to the first owner, who kept great records . Failed again on me at about 150k. interesting that it did last about 100k the second time around.

 

So how did you guys attach your ss hoses to the fuel tank? Did you use the stock metal fuel lines? If so how did you convert the 5/16" (I think) metal tube to AN? Ive been wanting to do some upgrading of my fuel system but I cant figure out how to go from the tube to the SS hose. I saw that earls has an adapter that will do it, but it is listed for no more then 25 psi.
