Toyota Yaris Fuel Pump Specs

Neinris, please let me know if you feel the info is pertinent. If not, I don't want to steer the thread off in a direction that you hadn't intended. I can remove or edit anything I post.

Note that the 2007 pump has an amp draw and 5.68A and a max pressure of 50 PSI. The 2009 pump has an amp draw of 10.68A and a max pressure of 100 PSI. The 2007 pump delivers 29 GPH and, oddly, the 2009 pump delivers 26 GPH. Since they are both Delphi pumps, I would expect the spec criteria would be the same. I am not sure if this actually means that the 2009 is a more robust pump capable of delivering more fuel at higher pressure. All pumps below run on a 44 PSI system pressure.

Here are the specs for a 2007 Delphi fuel pump:



Here are the specs for a 2009 Delphi fuel pump:




I wish there were specs on the pump body dimensions (diameter and length) published. The specs above are from RockAuto, but I also found data on the Delphi website:

For comparison purposes, here are the specs for the 2013 RAV4 (2.5L) Delphi fuel pump:

Yes! These are very pertinent information. Thanks Adam! I guess normal operation they all pump at 44psi? The RAV4 is obviously the best pump of the three, it’s well rounded. I’m not even sure if going beyond that is even necessary. Thanks to your link I checked out the Venza’s fuel pumps, the 2.7L I4 and 3.5L V6 DO NOT share the same assembly. The info for the 2.7L (the one that I was going to experiment with) is incomplete, doesn’t mention the max pressure, but it says current draw average 10A, and average flow rating is 40gph. The RAV4 still beats it. And for the 3.5L V6, average current draw 8A, average flow rating 65gph, max pressure 80psi. It’s slight better than the RAV4, but the pump(motor) housing(canister) won’t work with the Yaris’ fuel pump assembly basket. So that’s out of the equation.
So, I believe that if you have the 09 Yaris fuel pump module assembly, you can drop in the RAV4 fuel pump motor. This is where the experiment starts. Maybe have the part store bring both motors out and compare dimensions. As far as filter, just used what’s made for that motor.

For the 08 and below, I don’t know what would be more cost effective, buying the 09 assembly and then getting the RAV4 motor, or just buy the RAV4 assembly and Frankenstein the basket with the top canister? But that involves having to unplug the hoses and swapping them. Not sure how to properly secure them afterwards???

Any more thoughts Adam? Thank you very much for your input. It narrowed down what I want to do.
