might be dumb question...but iam brainstorming and cant think this out.
Running a return style fuel system on my 2004 mach1 mustang
fore rails, y split, regulator (f2) 3 walbro's pumps(fused and wired) in fore manifolds with two jegs filters (one in and one out)
-10 from tanks to pumps, -10 from pumps to spliter, -8 to rails, -8 return.
using glenns sumpted tank and have the evap stuff installed (i had to buy new stuff cause Iam NOT breaking the old stuff again)
anyways...
I am putting the stock hat back in the tank with level and sending unit correct? how to I cap off the open lines on the hat?
OR do I do something else? everyone has been super helpful with getting my project done and Iam getting closer and closer
 
just cap the lines , rubber caps will be fine


might want to rethink your -8 return size, or at least keep it in mind if you end up having a pressure creep when it is all together

-10 feed and -8 return has been proven time and time again. any smaller the -8 you would have pressure problems.

YEAH.. i just did what john tymensky recommended for my set up...he actually first recommend -12 out of the tank to the pumps. ...But I already have everything for -10.

now gotta post my cobra tank and pumps in for sale section...
