Dead-end capable: depending on the unit, no return is required.Self-regulating: meaning only the amount of fuel demanded by the engine is supplied by the pump, up to 58psi.Supplying these engines is a Modular Reserve Assembly-style pump and assembly. The Holden VE Commodore was manufactured from 2006 to 2013 with a range of engines available, from a 3-liter V6 producing 175kw / 240hp to a 6-litre V8 producing 270kw / 360hp. This can be easily achieved on the RA28 Celica- and likely many other cars – by using the Holden VE Commodore modular reserve assembly (MRA). This solution, while more time consuming to set up, is neater, quieter and arguably safer than running an external unit. This solution is simple and easier to set up but can be unsightly, noisy and release fuel vapours into the air and cabin.Īn alternative solution is to convert your fuel tank to run like an OEM fuel-injected car: by installing an in-tank fuel pump assembly. One solution is to run an external pump setup, lifting fuel to a surge tank that then is pumped to the engine by the main fuel pump, such as the many Bosch or Walbro units. These engines are more powerful and require more fuel so an aftermarket system must be installed.
These engines require pressurised fuel to be pushed from the fuel tank by an electric fuel pump compared to the original carburetted engine which sucks fuel from the tank with a mechanical fuel pump mounted on the engine. Many RA28 Celica owners transplant newer fuel-injected engines into their cars.
