What is the stock fuel pressure regulator pressure set at in a 2000 Accent SOHC?

Is there any site that has pics of the fuel pressure regulator and its setup?

If I install an adjustable fuel pressure regulator can I leave the old one on or should It be removed?

On the stock pressure regulator, is there a return or is it a returnless one?

Any recommendations on an aftermarket adjustable fuel pressure regulator?

Thanks!!!

Per HMASERVICE, stock fuel pressure for a 2000-2001 Accent is 49.8 PSI. The regulator is actually attached to the pump itself and could possibly be adjusted. HMASERVICE describes a "fuel pressure too high" scenario resulting from a "sticking" regulator. I'm sure you can find a creative way to make the regulator "stick".

Not sure if its a return/returnless regulator but it kind of sounds like it might be. HMASERVICE makes reference to Clogged, bent, and leaky fuel return pipe/hose. The pics on http://www.hmaservice.com/webtech aren't very good but you should be able to find detailed installation/removal instructions.

Tried to get the answer to your third question a couple of weeks ago. Couldn't get a definate answer. I heard SuperStreet did a "How to" on fuel pressure risers in their current issue. You might wanna start there.

I plan on going with Weapon-R's fuel pressure regulator (universal unit will be ready in mid-late November) only because it has a pressure gauge attached to it. The attached gauge should make fine-tuning adjustments a little easier.

Thanks 1SickGS,

I missed the info on HMAservice about the fuel pressure, pressure level.
Do I need to remove the old pressure regulator or can I just add on a universal one after it? Because if the pressure is set higher than the original one and the original is still feeding the universal one won't the pressure be too low coming into the universal one from the original pressure regulator <img src=icon_smile_question.gif border=0 align=middle><img src=icon_smile_question.gif border=0 align=middle><img src=icon_smile_question.gif border=0 align=middle> (that was confusing enough, hope it's understandable).

Weapons R is a bit pricey, but so is Holleys. They're both around $200.00. I've found one for around $100 and $15 - 25 more for a pressure guage. Having the pressure guage built in is nice though.

Purchased an Autometer Air/Fuel meter, getting ready to install it. Now I need to figure out a good place to instal it in. One that it can be seen, but doesn't stick out like an eyesore.

I understand what your saying about removing the stock fuel regulator. Thats exactly what I'm trying to figure out too.

You should be able to get weapon-r's regulator for $155 at http://www.importstudio.com but, like I said, the universal ones aren't available yet.

I'm still working on my A/F meter too. I mounted to the a-pillar using an Autometer Gauge cup. Came out pretty OK. I'll post a a couple of pics later today.
