Problems with purple diff lock hose under backseat, ABS flashing

[Jonas_R]

Well,

My purple diff lock hose under the backseat was broken (had a hole in it) so i repaired it by cutting away the damaged part and replacing it with samco hose. But know every time the car sees boost the damn ABS lights up. Now this makes me think that something is not right

Perhaps the check valve is broken or what the hell could be the problem?

The valve that connects to the purple line is a one way valve right? Because this valve aint one way anymore So Iam getting boost through here Can I just plug off the hose coming into the one way valve? Or will that damage something?

Have you tried getting hold of another check valve?

[Jonas_R]

Hi Greg,

Sadly I dont have the time to get another valve by tomorrow. Since the car is getting mapped. But the valve is ******, i checked. Anyways now I have blocked off the hose coming to the valve and now the system holds pressure just fine. I guess this will mean that the rear diff lock wont work but I aint using it anyways

Yeah must admit ive only used the diff lock once I think, does it help with 1/4 mile launches tho?

Hi, New here at the forum, but yes it helps 1/4 mile launches too. if you got more power than original. it gives you a proper boost of the line=)
