hmm old post that nobody could anwser too bad i didnt see it sooner, i checked out a supra pump for my civic a while back,it flows 275lph .

i think its 260 or 290(depending on voltage) i cant remember exactly

mkiv's have a two stage pump.

yeah,thats why i didnt use it,i figure itll shorten the life of it if it ran on a constant 12 volt

Cool deal, better late than never . Ashame I sold mine I while back and kept my walbro 255. Jason

if you need more lph and want to keep the intank fuel pump you could always run one of those voltage raisers like the kenne-bell boost-a-pump,aeromotive fuel controller and i believe msd has one,they raise the current too like 18-24 volts without heating up the fuel. with one of those an walbro 255 would go well past 300lph,i bet probably close too 400lph.

I ran a bosh relay, instead of main relay, voltage went from 10 volts with main realy to 14 volts with a deticated relay direct from battery. Pump sound a whole lot meaner, and it has lasted for 2 years that way.Jason

i ran a relay to my stock intake pump and it got a lot louder i was only getting 9.3volts so the pump at first now am getting 13.8volts

DLB, could you please tell me what relay, where you got it, and how much you got it for. Also, what wires did you tap into?

SEFIxCivic

you can buy a bosch relay @ any stereo store for about $1.75

i am runing a 95supra tt pump in my crx, i ran bigger gauge wire and a relay with the 12volt mod, the pump fit like stock i was even able to put the stock sock on it with no modifications, cant even tell its not stock
