Driving with broken ACD pump

Sadly, My Evo got hit in the left front corner by an oblivious soccer mom and now I need to limp the car a decent way to get it to an adjuster and body shop (I live in a remote area). Anybody have advice for driving with a broken ACD pump? Can I tape over the openings, fill it with diff fluid and hope for the best?

That's the solenoid that got broken there so I suspect if you unplug the pump so it doesn't try to pressure up you should be able to limp it to safety.

take the pump off, cover the connectors and hydraulic lines so that they do not get dirt inside and drive normally. No need to add oil anywhere. Car will understeer more on the limit.

Just unplug the electrical connector nearest the solenoid?

To the pump itself so it gets no pwer.
And start your solenoid/pump quest now. Solenoid is really hard to find, I got mine from Russia years ago but that route is currently unavailable.

Been doing it for 10 years lol. They make rebuild kits for it. I think I paid like 400 bucks for a new pump and the lines to put it in the trunk.

Lol get an ic-7 fixes the lights problem. At least you didn't **** up your pump after you got it off. Guys at the shop were told that don't touch the acd pump being one of the head techs was going to deal with it being he had to cut the studs off of the thing to get it apart and then remove the studs afterwards. Well they didn't listen and ended up trying to take a hammer to get the top half of the pump off and broke the top half off of it. Oh and by the way they don't make a serviceable part for it. Thankfully I can get a new piece that they broke but I am not paying for that. Specially since they were told not to **** with it.

Canadian company makes a sealed upgrade motor for our ACD pump, yes it's not cheap, yes I have one.
Don't mess up that solenoid either, no factory part, I got mine from Russia years ago so good luck with that bit.
Oh ACD pump, I know you so well and hate you so much.
British company used to upgrade the solenoid but not sure if still doing it.

Yeah i have got the new pump from Canada and my relocation hoses. I mean my pump housing is now broken cause of the dumb ****s trying to take it apart when they were told not to so I am going to let the shop fix that one. I know there are other places where you can get the solenoids. I think its a different company in Canada. I thought about replacing everything to make it all new but **** I mine as well buy a brand new pump for what it would cost me.
