Alright the pulsation damper fails a lot from what I hear but costs like $130 and you need to replace gaskets and things like that also when you do the instal. I have heard also that you can just eliminate it with a banjo bolt. My question is that how can a banjo be a replacement for the damper. I thought the fuel damper had a function of dampening the pulses in the fule system. Can a banjo do this ar is it not really needed?

 

bump!

 

If it was intended to have a banjo bolt it would have came with one is how I see it. I just changed mine, was pretty easy.

 

So it is actually needed. That is what I thought do you really need to replace the gaskets and stuff or should I do it to save me the trouble later. Got the part numbersfor everything needed

 

I didn't change any gasket. Well the one for the upper intake manifold. Not sure you have to even take that off if you have an NA. Your supposed to use some teflon tape though on the threads.

 

Ive been there, I figured that since my motor was running perfect with a broken PD, it prolly would so with a BB---Kim

 

So you have a banjo on your car?
How long have you had it like this?
does anybody have the frikin part number for the banjo bolt or someone that has a good price on the PD?

 

anybody?

 

Haven't been able to find a good technical reference anyone know of one? Hmmm, lets ask a moderator!!!!

 

Thats right it is the day of the week when a moderator blesses us with a guest appearance

 

hello?

 

Yah i got the Part #, I just picked my BB from Summit a few days ago, got it yesterday.

Just the bolt itself if not in stock. and won't be awhile, so i'll give u the Part # that comes with the BB needed.

Here is the summit part # EAR-807691

Is using the banjo safe though won't it hurt the fuel system because of the lack of "damping"?

 

has anybody used a banjo bolt instead of the pulsation damper and how does it work(good/ok)

 

Guys do any of you have a write up on the install of the banjo bolt. I am about to order it and I am planning on installing it when it arives by air mail. any help appreciated!

 

Ryde or Die,

If the car were intended to have

Intake** APEX Turbo timer**Nitto drag radials**Fluidyne radiator**RB FCD**Walbro fuel pump**3" DP/MP** 720cc secondaries**S-AFC**60mm GReddy p/w boost gauge** 52mm GReddy EGT gauge**52mm GReddy oil pressure gauge**GReddy Profec B**Turbo XS Type RFL BOV** GReddy FMIC

it would have come with them.

Somehow that justification never has satisfied me

 

I see your point, but I don't think it applies to this. The function of the part is removed when the part is. Adding performance parts doesn't really have anything to do with removing a functioning part.

 

The issue with the PD is safety. My Integra won't catch fire if its PD leaks because it is not over the exhaust manifold. My FC may catch fire, on the other hand, if fuel drips from its PD and gets on the manifold, as it is directly above it.

The fuel pressure regulator should serve as a damper in its own right, but it is on only one of the fuel rails. It damps the injector pulse fuel pressure spikes on one rail while the PD damps the other rail. I think this is to provide a consistent fuel pressure to the injectors rather than a pulsing variation in pressure due to its sequential release in each rail as the engine runs.

My fix to the PD will be to use a banjo bolt with a fitting allowing a hose to be run from it to a remote PD. Having the PD somewhere that will keep leaked fuel from starting a fire via the exhaust manifold is what I have thought up as a way to keep the factory damping but without the risk involved with its stock location. The hose should not be too long, maybe with the PD mounted on the front of the engine bay by the radiator.

 

I never thought about relocating the PD. It just seemed more logical at the time to remove it. I ran my fuel system parrallel so that every injector would get exactly the same pressure/volume so the PD wasnt really needed.

 

that is what I am thinking about doing. how did you
like it? what exactly did you do?
The relocation does make good since though. I should think about that. However this does not remove the threat of it accually leaking. Only the threat of it leaking on the manifold.

 

sorry this doesn't pertain to your topic but i didn't want to start a new thread. i have a question about the PD failure.

when i start my car i can smell gas, but not after its been running for a bit. is this normal or should i be worried?

and is that bajo bolt & parts that is listed from summittracing all i would need to change out my PD to a banjo bolt setup?

 

Its much eaiser to show a link to a web page that can do a better job of explaining this mod than I could do by explaining. So here you are:
