I wanted to know what ppl do to there cars.

I have an aps extreme fuel system. There are two pumps and two feed going to fuel rails. one each. what happens if one pump screws up what do ppl do to fix this problem. so you don't lean out the one side?

 

run a y fitting.

however i know nothing of the aps setup, but i beleieve it to be 1 feed splitting off to both rails, and 1 return from the regulator to the pumps. AMIRITE?

 

There are two pump and two stainless lines going to each fuel and oem return. also there are two regulators too.

 

I converted to 1 regulator. Yes, you can run one side lean if there is a malfunction.
