can I run this set-up without using a fuel pressure regulator

[TheAButton]

Ok so I have a MAF translator with a 3" GM MAF, 550cc injectors, and I have a walbro 255lph fuel pump. So my question is that, can I run this set-up without using a fuel pressure regulator, I was looking to run about 16 pound, or what ever this set-up permits me to run. Any feedback would be nice thanks. I'm also running a 16g right now too.

I got the Street Tuned Motorsports Fuelab Kit for 219 with all the fittings and hose and free shipping it was a deal.

Many have said that you DO NOT NEED an AFPR with a 190 lph Fuel Pump or smaller. However, Many cars differ. If you car about your car, gas, or money... you should get an AFPR. I bought the new one from WEAPON-R for around $120 or so. Im running a 255 lph Walbro, and i was averaging 13 mpg. So0o0o0o.... do the math please.

Ha ha ha ebay rubbish. I hope no one runs any of ebay low cost poorly built steal from the real designer crap. Its bad enough I went with a b&m afpr temporarily until I upgraded my whole setup. I just got a fuel lab setup from tank to the end of the rail...No more b&m junk...

I'm running 93 octane, and yes i think i am running rich. I cant smell it as much when I'm at WOT but when I'm driving normally I can. I guess we'll see soon enough when i get my wideband.

If your gunna spend your money on a FPR, make it worth your while and buy a good one. Also, an adjustable one.
