how much horsepower are these things good up to ?? i dont want to have to drop my tank in the middle of winter, whats a good size one to get for a 1.7 gsr with a gm3 pushing 16 psi on about 460 cc injectors (might go bigger if needed) im just not sure how big of an electric inline fuel pump to get anyone have any problems with one ?

 

same with internal pumps. it doesnt make a difference, as long as the flow and psi are relative to efi and your needs

 

I have a 255hp external walbro (not a fake one, yes there out there!) on my 4wdr hatch
