Ask a question about this product

This is the famous Walbro 255lph that DSM and EVO enthusiast have been using for many years now. This fuel pump has proven to be a very reliable modification for all fuel types including E85. If you're not looking to go past 600whp on pump gas or 500whp on E85, this is the fuel pump you're looking for.

This Fuel pump has a relief valve in it from the manufacturer. If you need more fuel please push in this relief valve to receive an additional 10-15% more fuel flow. This pump will outflow other competitor 300lph pumps once this modification is performed. We also offer this service for an additional fee.

TSComp Spec Double pumper (Dual Walbro 255)

Brand: TSComptuned / Walbro
Availability: 2-3 day delivery
Starting at: $528.00 Shipped

After many years of selling other Fuel Pump Systems and solutions, We have designed our own system in house.

Having tested Evo's ranging from 300WHP to 1000WHP, We know what works and what doesn't with your vehicle. As most would not believe, A simple double pumper system and larger injectors will take your STOCK fuel system over 800WHP+. Your stock fuel lines can stay the same, And your stock fuel pressure regulator and stock rail are perfectly fine.

Upgrading the fuel rail will however, allow fuel to evenly hit all cylinders better than the stock rail. However, The stock fuel pressure regulator cannot be beat, So don't waste your time messing with aftermarket regulators unless you use a larger rewired fuel pump such as the Walbro 450, which indeed will overrun the stock system and not only requires upgrading fuel lines to work properly, but it also requires an adjustable regulator. Along with cutting out the fuel filter on the housing in order to function to its fullest. Sometimes aftermarket Regulators cause unstable fuel pressure, which then can lead to poor drive ability.

After modifying your system to work efficient with a single 450 pump, You're almost at the same price point as one of our double pumper systems will cost you, and I guarantee your car will run smoother with our setup vs the other methods. We are one of few shops who can still make a 800-900WHP+ Evo run like stock with the Stock ECU or Aftermarket ECU. As long as you follow our guidelines, you will experience a flawless running car.
