Genuine Walbro/TI Automotive F90000267 450LPH E85/Gasoline Compatible Fuel Pump GMC Sierra 1500 4.3L, 4.8L, 5.3L, 6.0L 2004-2009
All new for 2011, the Walbro F90000267 450LPH pump is the highest
flowing intank fuel pump on the market, and is E85 safe to boot (completely
compatible with both E85 or gasoline). Walbro designed the pump to meet the
requirements of modern high horsepower naturally aspirated, supercharged, or
turbocharged applications where a single 255LPH or 340LPH fuel pump is
insufficient. The pump uses a turbine style design which incorporates two
composite plastic blades, just like our HFP 255LPH pumps, as well as the
Aeromotive 340LPH pump introduced last year, however producing a staggering
450LPH! The turbine design lends itself to extremely quiet operation, especially
compared to Walbro's previous "gerator" GSS series 255LPH pump design that had
metal gears which were notorious for a very loud whining noise which could
sometimes be heard over even the loudest aftermarket exhaust setups. The Walbro
F90000267 lends itself especially well to daily driven applications which see an
increasing percentage of ethanol infusion.
The Walbro 450LPH F90000267 pump can flow anywhere from 15-120psi (the bypass valve is set higher than Walbro's previous fuel pumps, which were around 85psi). Final fuel pressure is determined by your fuel pressure regulator. Please note that this is an aftermarket fuel pump, and some modifications may be required to get it to fit. The overall size is very similar to Walbro's previous generation GSS340/GSS341/GSS342, however the base is slightly enlarged as shown in the pictures. Please email us with any installation questions. We specialize in fuel systems, and can help out with any questions, or small parts you may need.
