Alright so I'm starting my 2JZ build, I havent found anything relevant to this which is why I'm asking so don't "flame" me I'm just hear to learn like everyone else. So I plan on using a Walbro 255 in-tank fuel pump and my question is considering my modest power goals of 500hp would I need a in-line fuel pump/fuel filter?

 

are you using stock basket? If so, isn't the filter built into that?

 

I would suggest a -6 fuel line to and from the motor.

No idea if the pump will support your needs

 

The filter is attached to the bottom of the walbro fuel pump not the basket itself but I've seen plenty of builds using in-line pumps/filters on top of their in-tank pumps/filters but all of these builds have been 800hp+. I specifically seen a build using two AEM in-line pumps running to a in-line filter but then again this was probably a 1000hp build which I'm not going for.
