I am not sure what pressure those are rated for ....


I would just suggest terminating with a barb and using a small runner of hose with a clamp.

on a awd tt 225ps if you keep the stock in tank fuel pump and add at the filter position a bosch 044 will you have starvation below the 1/4?????

Nope.

However, if you do that don't forget to add a 10 micron or better filter befor the fuel line

thank you for this

So, if I wanted to use my stock fuel pump to feed a surge tank, would I be fine just using the stock fuel line to feed the surge tank? Could I get away with using the stock fuel pump feeding into a Bosch 044 inline (with stock fuel filter before the inline pump)? This setup will be to support 700+hp.

And lastly, where did you find the Integrated Engineering surge tank (without pump) for $199?

So, has this thread, like, reached its maximum information output or something?
Bump.

stock fuel pump can feed a surge tank just fine at most any power level

stock fuel lines can feed the surge tank

I'm not a big fan of inline pumps..but you could go pump -> filter -> 044 ...and it'd work... But I'd recommend to go with a surge tank instead. Just seems like a much smarter setup.

I got the $199 off their website. Maybe that was an intro price. I don't know what it is now.

PS... IE and INA both make great surge tanks...but they fit different applications. So pick the one that suits your build best.

A question about fuel pressure.

On a stock 3bar fuel system like most of us around here, if you were to hook a fuel pressure gauge up, what does the reading look like through all the common phases of the engine. (not just readings, but if it bounces around, or is smooth, or what). I've never hooked one up to look but someone on here was asking a question the other day and I realized I don't know the answer.

1) You left your car in the driveway overnight. Gauge says...

2) You open the car door. You hear the pump prime. Gauge says...

3) You turn the key to the ignition ON phase. Gauge says...

4) You crank the engine and the car turns over. Gauge says...

5) You rev the car while in idle. Gauge says...

6) You go for a drive and you don't really get into it (<5 psi boost). Gauge says...

7) You stomp on it. You are holding 1 BAR boost. Gauge says...

8) After stomping on it you suddenly release the gas pedal. Gauge says...

I think if someone can chime in and answer these questions from real world experiences it would really help some people out in terms of deeper understanding and better future diagnosis.

Thanks!

1) You left your car in the driveway overnight. Gauge says... --------->0psi

2) You open the car door. You hear the pump prime. Gauge says... --------->36psi

3) You turn the key to the ignition ON phase. Gauge says... --------->36psi

4) You crank the engine and the car turns over. Gauge says...--------->34psi

5) You rev the car while in idle. Gauge says...--------->34psi

6) You go for a drive and you don't really get into it (<5 psi boost). Gauge says...----->36-40psi

7) You stomp on it. You are holding 1 BAR boost. Gauge says... --------->44psi

8) After stomping on it you suddenly release the gas pedal. Gauge says...--------->>34psi quickly


This is what I see...

..and 10min after you shut the car off the fuel pressure is back down to zero....

Yeah, I was planning on a surge tank, but was curious if the other setup would work or not. I am aiming for a simple setup, but still want reliability.

[GLiMKIV]

I'm looking to move my Bosch 044 to the fuel filter location however when I go to lookup the fittings on the badger-5.com site I do not see it. Can anybody tell me if those fittings/adapters are available elsewhere? If they are not available, would it be possible to just run 5/16 high pressure fuel line from the back all the way up to the front?

Thank you

Just curious, but what filter are you planning on running for your setup and where are you going to mount it?

I would like to use the original fuel lines if possible and then put a fuel filter inline. Just trying to clean up the engine bay a little more.

[derekb727]

Does anyone know the fittings required to run AN fittings for this A4 fuel filter?

http://www.ecstuning.com/Audi-B5_A4-...lter/ES258818/

[derekb727]

Just an update to the above.

the two fittings that you need are m12x1.5 and m14x1.5 with whatever AN size you want on the other I went with -6an.

I will post a picture up if I remember

[OLD GHOST]

just an FYI: Went to Summit yesterday to grab the Aeromotive 15117 fitting an it would not lock on to the stock MANN filter.

thanks. saw that one in another thread. now what do you recommend for the 90 degree to the stock fuel line?

What are you trying to do exactly?

If you're running the stock fuel line, why not just run 5/16" fuel hose from the factory fittings and be done with it?

...

Good option for factory hose...

Otherwise, if you've already converted the lines to -6AN male, then get a -6AN Female -> barb fittings

...

Again, what are you trying to do?

[OLD GHOST]

just want to replace one connector (filter side) could not locate a replacement (napa/autozone) so i was going to make one. However the C2 link looks like all i need. Thanks!

This is an excellent thread. I am almost done with my full stainless line conversion (hard and soft). This would have saved me a BIT of time.

Share this.

[jetta021.8t]

I know this thread is a little old but...

Is it a big deal if I don't change the line form the stock pump to the filter and just run a 3/8" line the rest of the way?

If I need to run that line what is the best line to use? Looking at doin the rest in stainless hard line.

Is it fine to leave the stock return line or should that go bigger?

At what point should I be looking at a surge tank ?hp? I'm just over 400whp like to go more.

Thank you for any help..

I'd run stock lines to the bay

Then in bay surge tank

[jetta021.8t]

Would that line be big enough to keep it filled and how safe is it to have that there on a daily drive car? I do run the inline walbro up there but I'm look at moving it back to the filter location.
Problem I'm having is leaning out as I get pass 25psi (a/f 13.4) .. Not sure if its a line issue or I need bigger pump , surge tank, or bigger injectors

[groggory]

Your lean out issue must be diagnosed.

Go start your own thread with a detailed overview of everything and lets go from there.


Ps... 5/16" (stock) lines can flow a lot

[jetta021.8t]

Ok thanks for the help

No problem

Well get you sorted.

I'm a bit confused....does this go on the barbed like oem quick connectors or straight onto the pipe itself like a pneumatic fitting?

I would like to ideally join into the oem plastic lines just low enough to be out of sight in the bay or underneath the car?

Cheers

They hook over the OEM fuel line... You cannot cut the OEM line or anything to make it shorter as they need the little lip thats on it to hook up properly, loks like this when on the Fuel line







Hope this helps you

[StaceyS3]

Cheers for the reply, that's answered my question

Does anyone know of any fittings that can be used to cut the oem line and connect to it

Cheers

Once you've cut the OEM line, what would you like to connect to it?

[StaceyS3]

Would like to go to -6AN fittings which will feed my surge tank but was just hoping to have the join out of sight

Contact USRT, I think they have that in aluminum
