Fuel pump/lines Need some advice
 
i'm working on a fuel system here (and it's my first) so any help would be appreciated. i was planning on running -6AN from my fuel tank hardpipe to a -6AN to -10AN coupler and run -10 from that to my inline pump and into the rails. I have the CJ Motorsports fuel system with 1680/1000cc injectors. Note that i already have a walbro in tank pump as well.

i'm going to be using an Aeromotive Eliminator inline pump... where would be the best spot to mount this?

any advice would be great

what power are you planning to run as those injectors are giant. at 85% duty cycle you would be close to 700hp according to a fuel calculator. if you are planning anything that crazy you better get a better fuel pump setup.

maybe u should consider an aftermarket fuel cell n mount it in the trunk...with two -8AN to a Y adapter to -10AN...just a suggestion

I'm hoping for between 650 and 700 whp, running a Turbonetics T-76 turbo. It's the same fuel pumps that crispeed uses in his FD and they work fine according to his video :)

i went with the 1680s so i have room for more power once my next emmisions date comes around. i know my car won't pass as it is but its still registered for another year and a half. once the emmisions date comes back around i'm pulling it off the road and BP the engine and putting a huge turbo on it.

it was a consideration


anyways i decided to try the walbro twin pump setup from CJ Motorsports and i'm going to run twin eliminators which should give me plenty of fuel pressure. sooooo where the hell should i mount these bitches?

Twin eliminators sounds like overkill doesn't it.

if you are running 2 walbros inside the tank, why run 2 more external pumps? 2 walbros will support the power you are talking about
