the supposedly brand new walboro 255 pump i bought from extreme psi on ebay is dying out. what factory fuel pump outta what cars will push enough fuel?
99'si b16/wt3 11psi,dsm450s'

 

is "extreme psi" a company or a person. cuz it should have a warrenty from a company...how long has it been in there?

 

How do you know it's dying?

 

the guy at the dyno where i got it tunned told me it was dying out. i had to purchase a fuel pressure regulator that day from a different shop cause even with the vafc going into +5 it wouldn't richen the air/fuel ratio cause the dyno guy said that the 10psi i was running was pushing some of the fuel back into the injectors. after the FPR was installed it did good but the more times the car did a dyno pull, more fuel had to be added cause the reading was coming in leaner. it was good by the time i left, but the dyno guy told me that if the engine was bogging after i turned on the car the next day after it cooled down that the fuel pump was dying and to tighten the FPR all the way so it would let less fuel in, just so i would be able to drive the car (without going into boost) no problems with it the next day though. i was just asking cause i remember him telling me that and discount auto has a special on fuel pumps right now. let me know what you guys think, i don't know much about this but i know i've been running 10-even 14psi in 4th & 5th and no detonation.

 

damn, i just installed my 255 walbro from the same company off ebay.extreme psi.

 

the pump worked good for a couple months. good luck.

 

my walboror also took a dive a few days ago. maybe a manufacturer defect. anyway im running a gsr fuel pump for now (while im waiting for my new one) which some people say can hold anywhere from 250-300 whp. we'll see. good luck

 

---- i bought one from the same company too. mine seems to be ok

 

well, i'm running on the walboro now though. i just got the FPR turned up a little to compensate. but it is way weaker now then new. i'm getting a new 91' supra auto zone fuel pump. they come with a lifetime warranty $104.00 new

 

I heard if you run your car under a 1/4 tank of gas it can mess up the walbro 255. True?
