2 questions:

1. I know that you're supposed to use the bottom half of the stock FPR, so I'm assuming you also have to use the piece that the spring rests on, correct? If I do have to use it, what if it's kinda worn? when I took it apart, some of the surrounding rubber doesn't look really healthy. Should I replace it?

2. After fitting on the FPR, it's kinda loose. if the spring isn't compressed very much, it moves quite easily. Is this normal, or did I install it wrong?

 

anyone?

 

anyone use this FPR that can help?

 

if the rubber looks worn dont use it...... those type of regulators (b&m, eriks) are piles of trash... get a complete regulator.. aeromotive or aem

I'd hardly say that they're "complete trash". If installed correctly, the B&M (I don't have any experience with Erick's) works just fine, and is perfectly sufficient for most people's needs.

 

B&M=Eriks

they are problematic, i have seen those things break more times that i want to think about. not only that but the stock diaphram cant handle but so much pressure, it will break if you up the pressure (which is why you bought a cheap *** requlator in the first place right..?? )

You're right in that it isn't the best option if you'll be running very high fuel pressure, but for adjustments within a reasonable range, many people will (and do) find it to be fine. FWIW, I've read of people having problems with the much more expensive AEM units on a few occasions as well.

 

yeah, the early aem units had problems due to a bad supplier..... i yelled at em when i was out there last summer. i havent heard of any failing in a long time though.

IMO, you shouldnt ever really need an aftermarket FPR unless you have a big *** fuel pump that is over running the stock one.... its a bandaid for injectors that are too small

I was actually going to mention that in my last post. It's one thing if you want to move the pressure around on a relatively mild setup with stock pump/injectors, but you're right - more "extreme" setups should definitely make use of larger injectors and a better fuel management system.

 

i say you get a b&m or ericks if your not going to turn the pressure more than 43 psi or so. that is high IMO anyway which i see so many ppl run with stock cams and compression. i have a b&m and turned the pressure down which works well for me.

the stock diaphram like someone said is too small for high pressure, plus your just gonna kill your stock injectors going higher than that if you have stock injectors.

if you are planning a bigger setup or have one already, and want to upgrade the pump, i would just get an aem fpr.

 

wow, i had no idead that the Ericks was so questionable. Here's my setup... let me know if you guys think I need to change FPR's. If this FPR will do though, I'm gonna stick with it. If I gotta change it, I'll change it.

'94 GSR
*Fuel*
-Walbro fuel pump
-440cc injectors
-Hondata
*engine*
-P&P GSR head
-skunk2 stg2 cams
-11.8:1 compression

 

I dont know about you but I run my b&m at 51 psi on my setup. Check my sig for details...

 

is your b&m kinda loose when the springs not really compressed? I can turn the FPR pretty easily right now, and I'm just wondering if that's normal.

The stock FPR is adequate for your setup. You can add plenty of fuel with Hondata and 440cc injectors, without upping the fuel pressure.

damn... i already hacked up my stock fpr to fit on the Ericks one. I guess this is what I get for not doing more research. Since I already have the Ericks one on, it isn't gonna hurt me to have it, is it?

Nope.

ahhh, that's a relief. Well since that's out of the way, can someone tell me if it's normal if it's kinda loose? It's just seems odd how I can turn the fpr without much trouble.

you will have to modify that unit to handle the extra output of the walbro pump. Do a search on the forum to learn how. Or look on Endyne's site

Wow, thanks for that!!! I had no idea that I had to modify them. Just to be sure, is this the correct article? http://www.theoldone.com/articles/regulator/?
