Default D/B series Fuel pump

so I recently did a Jdm 00 B20B swap into my 99 ex , After a day my fuel pump wasn’t priming anymore. My stock Fuel pump on the ex was already having problems so im guessing it just went bad. What Fuel pump should I run with my Stock B20 ? Only bolts on I have is a Aem Fuel rail and short ram intake

255 is too much for a stock motor and fuel pressure regulator in my experience. It can cause you to run rich.

I think egsleepercivic means with a stock ECU... however, if you have a tuning solution, the elevated fuel pressure can be compensated for.

simple $40 blox fuel pressure regulator would fix that. But yes tweaking the tune will do it too

For my B20b in my integra, I wanted a little upgrade so looking at the info in the following thread

https://honda-tech.com/forums/acura-...-info-3166803/

I went with the Denso 110 lph

Amazon Amazon

Works fine no issues, I plan on using the same pump in my 93 si with B16a

good luck
