I was looking at this fuel pump the other day and had some questions. I tried researching it but there isn't much info on this pump. I know the walbro 450 is better but I didn't know if it was overkill for my build. I'm looking to get 500-550whp on my fully built ls. Will be running e85, aftermarket fuel rail, fpr, and either ID2000's or FIC2150's. Was looking to save money and spend it somewhere else if the aem pump would support my build. Any info would be great. Thanks a lot Honda tech!! Also I will rewire this pump won't use the factory baby wires.

 

I made 550 on the aem 320 regular pump with all stock lines.

If your gonna run a single pump I'd get the walbro 450 but if you def will be 100/ happy with around 500 then the 320 will support that power on e85

 

Theres also the walbro 416lph e85 version. Overkill is a good thing when it comes to fuel pumps
