Fuel Pump Upgrade
Tuesday, June 10. 2008
Since the TRD supercharger delivers a lot more CFM to the engine over stock, and since others have tested and proven the stock fuel pump to be inadequate, I've upgraded the fuel pump to a Walbro 190 lph.
I raised the bed, letting my engine hoist do the heavy lifting.
That gave me access to the fuel pump bracket.
I removed the fuel pump bracket. Here it is with the stock pump.
And here is the Walbro 190 lph kit.
I soldered the old and new wiring harnesses together, then protected the joints with heat shrink tubing.
The Walbro pump is a bit taller than the stock pump, so with a tube cutter I shortened the fuel delivery pipe about 1/4". (Sorry, no picture.)
Then I mounted the Walbro onto the bracket.
I reinstalled the bracket to the fuel tank, and the engine fired right up and ran smoothly. Next up .... some maintenance.
