Str8JDM · 01-24-2012, 11:08 AM

i have the dw300 now, it was done the same exact way wit my 255

***aLmk*** · 01-24-2012, 11:28 AM

Alright cool. Hopefully a fuel return with the ID 1000cc's, and walbro 255 I have will be enough to support e85 up to ~400whp.

Str8JDM · 01-24-2012, 11:37 AM

hmmmmmmmmmmmmm it should...

my last setup, 255, FIC 1000s, fuel return setup, 517whp using 61% injector duty

***Fsrider*** · 01-24-2012, 02:17 PM

If my duty cycle is at 90% with 520's sc'd how much do you think it will lower the duty cycle?

snizzletoff · 01-24-2012, 03:11 PM

you really don't need a return system you could just upgrade your injectors.

***Fsrider*** · 01-24-2012, 03:21 PM

Fuel return systems are so much better for boost and tuning, will be upgrading the inj's as well.

So Brian, did redoing this fix your weird pressure issues?

Str8JDM · 01-24-2012, 04:53 PM

Great DIY man, good job!

Sub'd. Very useful and helpful DIY. I have plenty of knowledge on this stuff, but it is excellent to know exactly how to do it on our particular car. Awesome. I only recently found out that we can just use the OEM feed line as the new return. Very nice.

When you put in the regulator do u have to adjust anything or is it pretty much pnp?

dil2502 · 01-27-2012, 10:58 PM

i think if you have an adjustable one. they have a screw to adjust the base pressure you want to use

Str8JDM · 01-27-2012, 11:20 PM

all external regulators to my knowledge has an adjustment screw so u can set the base pressure. +1 to you ^^

dil2502 · 01-28-2012, 12:11 AM

yea!!!!

***aLmk*** · 01-28-2012, 12:17 AM

Ans when hooked up they automatically adjust for boost 1:1?

dil2502 · 01-28-2012, 02:39 AM

yeah ones that reference boost. i believe they are called raising rate regulators

fre$h si · 01-28-2012, 02:48 AM

What are the nipples for that r on the regulators?

It's so you can have the regulator increase fuel pressure relative to the boost level. 1:1.

My .02, if your not shooting for over 500whp, theres no need to run a hose all the way back to the tank for the return. put the hose into the OEM feed line on the firewall like in the pictures and it will save you money and work just as well....

so if i use the original feed line for the car for return line ow do i install the feed line?
