The walbro 255lph pump in my EF is going out.

I want to upgrade.

The 2 options I'm looking at is Deatschwerks DW300 320lph or Fullblown Motorsports 340lph in-tank fuel pumps.
Both companies only make them for EG/EK/DC.... not for EF.


Does anyone know the differences between EF & EG/DC fuel pumps such as:
- connector
- filter/sock
- inlet/outlet

What do i need to do to the EG pump to make it work in my EF?

you sure you even need a 255? a 190 will support over 400hp and is quiet(er)

i already have a walbro 255 but it's going out already... not sure why maybe bad wiring but it's not holding fuel pressure like it use to

idel fuel pressure is only 20psi...
WOT goes to 40psi but drops back down to 20psi after about 6500rpms...

Check your regulator. How old is the pump? I doubt the Walbro is bad, but do a power check on it: run power straight to it and look at the fuel pressure gauge and see what it says. What regulator are you running?

when was the last time you changed your fuel filter too?

if you are actually wanting to go with a bigger pump, i suggest the Aeromotive

Hey peiku,

Do you need more fuel than a 255LPH pump can provide? We (DeatschWerks) have our DW200 that is a quiet, ethanol compatible 255LPH pump.

I have a DA assembly and a CRX assembly in house and I've looked at the fitments before for both my CRX and my Wagon.

The part I don't have available is the fuel sock. If your fuel sock is still in good shape, our universal kit will provide everything else you'd need: electrical connector (you already have with the Walbro install) and fuel hose and clamps.

I could snap a pic of one of our pumps installed with the OE fuel sock if you'd like to see.
