Just as the title says when I am boosting and the meth kit kicks in my rear windshield starts spraying based on how much boost I am at.

Is pump pressure to much creating a back pressure and forcing meth out of the closest exit point (rear washer)?

 

Your joking right?

 

nope dead serious, it looks like the car is taking a **** on the back window

 

haha best post on Evom I have seen in awhile...

to the OP - sorry man, I wish I could help. Thanks for sharing anyway, and good luck. If I had to guess I'd say someone the injection kit was hooked up to the same switch/actuator your rear window sprayer was on and some lines got crossed somewhere... But thats just my uneducated guess.

 

Or he is using the windshield res bottle and kept the rear windshield lines on? :-X

 

 

wow. i can see what razor said though.

 

rofffffl..

did you figure this out man?

 

HUH? can you show me how you have this wired as well

 

Wiring on the Snow pump is not touching anything on the reservoir other then putting the meth line into the reservoir everything is still stock.

And its not like the washer starts spraying full blast, it just drips out then as boost builds more and more, fluid sprays out more and more...

I am thinking of un hooking the rear washer water line to see if it comes out the front this time.

 

Sounds like your washer pump is getting a feed from the meth pump. The more voltage your meth pump gets the more voltage your washer pump is getting. It sound like there is something wrong with the wiring or meth pump earth.

 

I have been thinking about this for sometime. John F's explanation is more likely, check the grounding wire between the two pumps.
