okay so what do you suggest for a return style and why am i better off? Not questioning you i just like to learn.

 

I am running twin external Walbro pumps, 60lb injectors, 10 -AN feed 8 -AN return lines, Granatellin fuel tank insert, UPR fuel rails, paxton fuel regulator, Aeromotive fuel filters

 

so you have one pump than the filters than the other pump correct and what size pumps are they?

sorry if im being a pain in the a$$haha. I just wanna get this all figured out so i know a ball park figure as far as prices.

 

Filter-pumps-filter
Both 255 lph
Second pump comes on at about 5psi boost
Gonna run you around 1400 or so, adds up especially the numerous fittings

 

Lizzy, you would know better than me, but aren't the external pump systems supposed to be gravity fed? I figured that's why people always sump the tank rather than use a hat like the setup you have.

 

OP if you are happy at or just under 500 rwhp you can use stock fuel lines, SVT pump and BAP, I am also using 60 lb injectors and you are good to go.

This is what I ended up doing as I didn't want to shell out another $1400 for additional power beyond 500 rwhp. Also if you are looking for beyond 500 rwhp you should go with a nice set of heads as well.

 

Once again, not gonna work on a return style system

 

hahaha thanks lizzy
