Fuel Pressure Regulator Replacement

Is it possible to bypass the fuel pressure regulator on the fuel rail without cutting the rail?

no there is not. sorry but you have to cut it off to replace the regulator, and just my 2 cents it was quite easy hardest thing was cutting the pipe with my air body saw as its a normal size one and not the baby version

^^^ Yeah, just do it. Seems like it will be painful, but it's not that bad. I put a new NISMO adjustable fpr on the firewall and didn't look back.

Or if you have access to fabricator you can have a custom rail made....

Wow! you paid $250.00 for a fpr?

??

if the ca18et fuel rail is like the ca20e. i think it is. then its a easy job. its kinda a bitch to get at. but once you got the fuel rail out onto a bench... just cut the fpr off and flange it with a special tool(cheaper then paying someone). it took me a hour to convert my ca20e fpr to aftermarket afpr. If i knew it was so easy. i would of done this modification a year ago.

He probably saw a list price on a Nismo fpr, they are PROUD of their products. I searched and found one for about $120, still out there. Egay has all kinds of chinese knockoffs, only about $15-75. I got one, but wasn't happy with the results, so I squeezed out some greens for the Nismo.

How much work is about a removing a stock fpr ?

you have to cut the rail, cus the old FPR is attached, and re-route the lines to the new one.

Pulling the fuel rail is kind of annoying cus the throttle body gets in the way.  I used a dremel and a cutting wheel and cut it in place... obviously relieve the fuel pressure first or you're gonna have a real good time, lol

DO A SEARCH!! several posts on this, including one I did with pics..   

Edit:

A couple pics of what I did

I used a "one sided" hacksaw, a cheap blade holder that secures a hacksaw blade, to cut the tubes. It did the job with the rail in place, as I did not want to disassemble the whole mess. I was careful to leave a lot of tube on the rail so there was ample surface for a hose connection.

hacksaws suck for cutting such stuff

go buy a pipe cutter


5-10$............. which makes your life sooooooo much more comfortable :laugh:

no shit, after buying a small one i fell in love and bought a Monster Version 2"-12" :yes:
Intercooler pipes? 10mins
Exhaust pipes? 10mins

you dont get any shavings and the cut will allways straight and clean.........yep i really love this tools

Good call. I had to go with the saw cause of a space issue-called lack of. But in a more sensible world it would be best to remove the assembly and use a tubing cutter. In regards to shavings, I cleaned off the burrs left by the saw action, then turned the key on to pump some fuel out of the fresh cut, clearing any debris. Sometimes laziness works  :yes:

You aren't limited to Nismo, Aeromotive makes a kick-ass FPR in a variety of sizes, and the simpler models are cheap and work well, and are very adjustable.
