how much flow can the stock fuel filter /banjo bolt support? Ill be replacing my fuel filter soon and thought this might be a perfect time to upgrade (if necessary). Mods list below

Evo3 @ 21 psi
Walbro 190 rewired
RC 550s
SAFC2
RNR 3" TBE

I have no exact figures to offer up but I would have to say that yours will have no issue what so ever keeping up. I myself run a 255 without issue.

Not to dispute you but I've heard the 450's are close to overrunning the stock fuel delivery system at full IDC.

He is talking about the actual volumn of fuel that can flow THRU the stock fuel filter and banjo bolt. Not what size injectors can the stock pump support.

Oh I understand his question. The 450's can close to outflow the banjo setup. Now the stock fuel lines without banjos can flow quite a bit.

See the Stevetek.com article.

I thought I recall correctly but I could be wrong too. It has been know to happen.

Yes you should be fine, you have a 300whp setup tuned correctly...

If you would like to go all out with a higher flowing fuel filter and -6an lines throughout, go ahead man it will flow great! But its honestly overkill for your evoIII powered car..You might get a little more life out of your current 550/190 setup before you have to ugprade however

Agreed Josh, but a simple upgrade to the fuel filter and line to the rail should suffice. No need for the full tank to filter line for what he's running. He can get away with the stock system but its not optimal.

That is a good article. I guess once I move up to a 57trim and bigger injectors then I will have to seriously look into this.

I wish I found this before, thats important shit to know. I was thinking about using dual fuel filters in parralel. Sounds like a reasonable idea.

Once you remove the restriction that is the Banjo bolt on top of the stock filter the system is quite good.

I'm sure there are more than a handful of cars running 10's on the stock style filter/lines.

What I'm wondering is if a AFPR is recommended when doing the 10 guage re-wire and installing a Walbro 190 fuel pump to keep you car from running rich? The 190 and 255 warblo pumps are the same $, any suggestions/advantages of one over the other? Here is an ebay link for a line that replaces the banjo fitting; http://cgi.ebay.com/ebaymotors/ws/e...l?ViewItem&ih=015&sspagename=STRK:MEWA:IT&viewitem=&item=250103996669&rd=1&rd=1

Is there a way to piece together your own line without steel braiding so on could be made for less then 65$? Like by using the exisiting line running to the fuel rail and then cutting off the banjo fitting and replacing it with fitting you purchased?

No need to run an AFPR with the 190 or re-wire. 255 will flow more than the 190. Just depends on what you plan on running. I'm sticking with the Evo III so the 190 is just fine. If was running a 50 trim or larger, I'd probably go with a Whinebro 255 and an AFPR.

I've heard of that being done before.

here's a link to a site I found from someone's post.http://www.anplumbing.com/shop/
I figure all you would need would be the right size adapter to screw into the fuel filter and then the right sized hose end to splice into the existing fuel line that goes into the fuel rail. Anyone have any idea what the right thread would be and the right hose size would be? Maybe even the part numbers.

Stock fuel lines will take you to 500whp, probably more. Just get a hi flow fuel filter.

how much flow can the stock fuel filter /banjo bolt support?
