does anyone know what high flow intank fuel pumps are out there for a 91 CRX Si? I checked Holly and JR and both don't carry any for that year. I called JR and was told that you can use a 92-> civic/integra fuel pump, but will need a extra sleve to make it fit right, but really want something that fits... any sugestions?

 

cuz they arent in-tank... try a walbro external like a 155 L.. dont go big unless you have a reason to

I second that thought... everyone I know recomends walbro.

Definatly dont do it unless you need to and Im not talking about you have a fuel press reg and a fuel rail with stock injectors. I just replace mine on my 90 si equipped with a zc (thats fixing to be thrown to the curb for a built b16) but I have injectors a fuel rail a press regulator, alot and the stock pump. 200 buck though, cool that I didnt pay for it. DOnt ask why I have all this fuel flow **** it dosent add one horse to a unbuilt unturbo motor, the idiot who owned it before me did it.

 

I'm jsut trying to re-do my whole fuel system (rail, injectors, fuelpump, regulator) i have found all the parts except for the fuel pump itself and the fuel pump currently in my car is about 10 years old (91
CRX Si). I have a B16 thats currently bogging at low/mid-range throttle... i've change the cap and rotor...i have new wires and a MSD with a blaster 3 coil with 1999 Civic Si platium plugs. you guys think it my be my ignitor?

Clynders 2 and 3 spark plugs has white residule compared with 1 and 4 which look normal.. i'm commin to the conclusion that it's the fuel that's not right in my car. does anyone have any sudgestions???

 

I would measure the air/fuel ratio first before i do anything. take a GOOD voltmeter ground the negative side of the meter and splice and connect a wire from the O2 sensor and connect it to the positive side of the meter. then to get a good reading is to drive the car start off in second and run second all the way while someone (or you) watches the voltmeter. the readings will jump around until you floor it. when you floor it as rpm goes up so should the voltage. Normal voltage is .700 to .950volts anything below this range you would need a fpr.

 

walbro is junk, however you can make it fit intank. get an endyn fuel pump or a supra fuel pump. they should do the job nicely and they can go intank as well.
