ABS pump bypass
I know that this has been done. I need to know the correct routing to bypass the ABS pump behind the drivers seat. I understand the benefits of ABS. I am having to bypass mine because mine was completely submerged in water for god knows how long and no longer works. It also leaks brake fluid anywhere that brake fluid can come out of it. Does anyone know the correct routing to connect the brake lines together to bypass the pump?

I don't know if they are all the same. On a 90 each side is it's own circuit. The right is the rear in and out, the left is the front in and out to each wheel. You will have to cut the front lines and reflare them or get some mess of adapters to use a standard flare t because a bubble flare t is not a thing that exists.

I don't know if it's true or not, but I read where this fitting can be used in place of the abs connections and join the respective lines together bypassing the pump: https://www.appletreeauto.com/METRIC...E-113-611-755/
It's cheap enough to get to try without breaking the bank.
You will also need a bias/proportioning valve on the back half to adjust pressure to equalize the braking.
