Introducing the Walbro 400 Fuel Pump!

Dynosty has had the pleasure of testing Walbro’s latest offering, an all-new pump flowing significantly more than the old Walbro 255 GSS341 / GSS342, and even the Deatschwerks 300 fuel pump and the Aeromotive Stealth 340lph 11142! Our testing suggests this pump will be enough to support 800+WHP, though we have yet to verify that on the dyno. These will be on the shelf in ~2 weeks and we are taking orders immediately. Now Available! Cost is $159 and it comes with filter kit and wires.

Please note the larger base on this pump, meaning it will not ‘drop in’ some applications such as the Nissan 350Z. Contact Dynosty for installation assistance on the 350Z.
