On the pump, if you can't get enough slack with just loosing the tension bolt, you have to loosen the pump!
Straight forward enough, there are about 4 bolts i think, but onr you can't see! it on the right if you look at it and is and at the top, there is a gap and the bolt is down the gap, you'll need an extsion piece on your socket to get at it!
Good luck!
