Radium Introduces Redesigned Evo X In-Tank Fuel Pump Hanger

New from Radium – the Redesigned Evo X In-Tank Pump Hanger. This hanger was designed with focus on function, ease of installation and fuel starvation protection. See more details below.

Official Release:

Radium Engineering has been hard at work redesigning the in-tank fuel pump hanger for the Mitsubishi Lancer Evolution X. Originally released in 2016, Radium’s in-tank fuel pump solution for the Evo X has been used all over the world. After almost four years of production, it was time to apply new technology and design methods to this product.

A clean sheet design was started in late 2019, with focus on function, ease of installation and fuel starvation protection. The result is a very different looking fuel pump hanger from the previous version, with many new features that put it way ahead of any others on the market.

The previous version of the Evo X in-tank hanger used a two-piece collector box that had to be assembled inside the tank during installation. This new version uses a single collector that fully encloses the fuel pumps and can be pre-assembled before installation into the fuel tank. Also, the previous version reused the steel hold-down flange that came with the OEM hanger. This new version, does away with that flange and bolts directly to the studs on the fuel tank.

As before, the new version of the in-tank hanger is setup to use one or two submersible fuel pumps. Several different models of pumps are available to suite the needs of a wide variety of applications. The chart below can be used to help decide which model of pump (or how many pumps) will be needed based on approximate flywheel HP.
Note: The Bosch 044 is NOT compatible with this in-tank hanger.

This product is also compatible with the Deatschwerks DW400 fuel pump in single or dual configuration. Please note that Radium does not stock DW pumps, so this configuration is only available as “pumps not included”.

The stock Evo X fuel system is perfectly adequate for a stock vehicle being driven conservatively on the street. However, when the car is modified for more power, or driven on a race track, major shortcomings in the fuel system become big problems. One issue is fuel starvation. The fuel tank is shaped like a saddle bag, with the drive line in the middle. This design is suffers from fuel starvation quite easily during aggressive driving. For this project, Radium redesigned the venturi jet pump system so that it does not become a restriction for returning fuel from the regulator. This ensures proper fuel pressures are maintained, even with very high flowing pumps.

Features:

  • Single collector that fully encloses the fuel pumps
  • Bolts directly to the studs on the fuel tank
  • Setup to use one or two submersible fuel pumps
