I just finished mine DIY. Replaced the pump. What you said on this page at the beginning mostly did not work in my case. My new pump did not come with bracket which holds it to the block. I dont know where you all getting those pumps that come with brackets. Anyways instead of doing like you all do, i just unscrewed the pump it’s self from the bracket and got another new pump there. Also the pump was held by some stupid screws that areen’t 13mm they more look like screws than bolts. I fighted them for several hours and finally got it. There are only 3 of them holding the pump. The pressure line doesnt screw all the way to the new pump, the bolt gets tight half way in . Luckully it doesn’t leak.
