correct routing for trim tilt hydraulic lines

Hi,

I'm trying to reinstall my trim / tilt cylinders on a dps-a volvo penta drive after i rebuilt them. I'm trying to figure out how to route the hydraulic lines in and around the bellows. the port lines seem to fit well by going between the exhaust and u-joint bellows, but the starboard lines are causing me major headaches. It almost seems like they want to wrap completely around the exhaust bellows, but this seems to create too much tension on the lines. I currently have them going straight up and back down, but now they want to pop out the side of the drive and risk getting pinched when turning. In this configuration there is also pressure put on the pump unit when turning all the way to starboard. couldn't find any info in the service manual. Any help would be appreciated! thanks.

edit: it does appear that the starboard lines loop around the exhaust bellows after a closer look at the second picture you posted. I hope my routing works out ok

thanks but it doesn't really show where they run after they leave the trim pump. I found a way to route them that seems ok - basically the port lines run between the two bellows and the starboard does as well (it basically forms a 180 loop between the two bellows). This seems to be the only way that it won't kink the lines. I believe there's a chance for long term wear on the bellows from rubbing, but there really doesn't seem like there's any other good option.
