Re: Adjustable Fuel Pressure Regulator-*Updated with Results*

I have purchased a AEM FPR as well as a Walbro 255 pump. Had my mac fit both.
Thing is when we were setting up the regulator - when we disconnected the vacuum pipe to adjust the regulator she battled to idle. So we just set it up on idle with vacuum connected. I am afraid that we might starve the car for fuel as we didnt set it as per TwincamSams instructions. Its currently running between 36-38PSi on idle and goes up to around 40PSi when i play with the throttle....

Please advise if I should turn up the pressure?

Re: Adjustable Fuel Pressure Regulator-*Updated with Results*

Oh and we took out the original reulator and connected new adj fpr straight into the rail.

Can anyone assist in checking and adjusting this for me?

Re: Adjustable Fuel Pressure Regulator-*Updated with Results*

When I fitted yesterday - Car definately feels stronger in the mid to low rpm and revs cleaner to redline.
I have picked up the pressure to just about 3 bar as thats the sweet spot for okes that have fitted....waiting to leave work to test tonight  ../../extensions/custom_smilies_2/img1/whistling
Took the ecu a couple of kms to adapt when i installed yesterday...let see how it goes  ../../extensions/custom_smilies_2/img1/ermm

Re: Adjustable Fuel Pressure Regulator-*Updated with Results*

anyone try this on a 16v? pbut the reason for low fuel pressure is for better fuel consumption

Re: Adjustable Fuel Pressure Regulator-*Updated with Results*

We took out original regulator and tapped some thread into the rail. Then we hooked it up to the regulator that way.

Turned down the pressure as car was way too heavy on gas- 207km off R300 gas  with no freeway driving just back roads to and from work ../../extensions/custom_smilies_2/img1/neutral
got her set on about 42psi and not as torquey as before but definately revs up quicker. Will report back on fuel consumption---> I also want to do some pvt runs and test which setting is the best. Results to follow...

Ok, 95 ron is also the highest over here in trinidad and tobago.

Re: Adjustable Fuel Pressure Regulator-*Updated with Results*

I got a SARD AFPR but the instructions that came with it is in Japanese! I want to install it without removing the stock FPR, how to bypass the stock regulator without removing it? isn't the stock FPR connected to the fuel rail under it? will the stock FPR leak fuel if it's not removed after taking the return line from it? it would be really help is someone can post some pictures of the lines connected to the AFPR without removing the stock FPR, Thanks for your help ../../extensions/custom_smilies_2/img1/smile

Re: Adjustable Fuel Pressure Regulator-*Updated with Results*

I figured out what you're saying about bypassing the stock FPR without using it so i thought that i should share this info in case someone else needed it, you should take the return line going from the stock FPR and connect it as an input for the AFPR and then connect the return/out line from the AFPR to the stock return line on the engine where the stock FPR return line was connected, now you need to remove the vacuum line from the stock FPR and start the engine and wait for it to warmup then set the AFPR to 3 bar then connect the vacuum line to the AFPR.

Re: Adjustable Fuel Pressure Regulator-*Updated with Results*

Guile,
I removed the original regulator as i feared that I wont get the correct pressure to the fuel rail.  Remove the two screws that hold the regulator:
http://i285.photobucket.com/albums/ll70/KAMZ20v/Randburg-20120416-00108.jpg

Remove the original regulator and you would fild the feed hole to the fuel rail Notice the return pipe on the left:
http://i285.photobucket.com/albums/ll70/KAMZ20v/Randburg-20120416-00122.jpg

We used a thread tapper to tap some thread into the hole so that we could screw in the fitting for the piping to regulator:
http://i285.photobucket.com/albums/ll70/KAMZ20v/Randburg-20120416-00125-1.jpg

Then the fuel line from the regulator goes on as well as the return pipe to the tank. we then mounted the regulator and connected vacuum pipe (red) :

Thanks for posting the pics for your AFPR setup ../../extensions/custom_smilies_2/img1/smile

I'm thinking of removing the stock FPR too but I will get a fuel rail adapter like this one http://www.ebay.com/itm/JDM-ALUMINUM-FU … mp;vxp=mtr
, this way i can go back to the stock FPR if i need it.

Re: Adjustable Fuel Pressure Regulator-*Updated with Results*

Hey guys, reviving an old thread here but it inspired me to install a fuel pressure regulator to my 4A-GE 20v BT today and I was very impressed with the results. I installed this sweet looking Tomei fuel pressure regulator and raised the fuel pressure to 44psi (3bar). After my first initial drive once I had finished the installation I was very impressed at how much of a difference the additional 4psi of fuel pressure had made. The sluggishness down low had gone and the throttle response had increased dramatically. The engine now responds when I want it to, instead of having to wind itself up from low to mid rpm like it used to.

All in all it has definitely made the engine rev more freely and respond a lot quicker. It's now a lot more fun to drive, especially around town. Proved to be a very worthwhile upgrade ../../extensions/custom_smilies_2/img1/smile

The set-up consists of:

* Genuine Tomei Type S fuel pressure regulator.
* Genuine Tomei liquid filled gauge.
* Genuine Tomei fuel rail adapter.
* Goodyear fuel hose & 4mm silicone vacuum hose.
* 2x 90-degree brass elbow fittings, 1x straight fitting.
