Crack in Hayward Super pump housing wth pics

Thanks Poconos. My real concern is the length of the plumbing (feet of head) as I have not been able to find how to definitely calculate this. For example I don't know if I should count the return line in the total feet of plumbing, since it is after the pump. If I only count the skimmer to the pump the plumbing may be as little as 36-40 feet, but if I cant the return line as well then it could be as much as 90 feet of plumbing!

Once I know if I can use just the skim line or if I need to use both then I can see what size pump I will really need.

I am stuck between the 1HP and the 1.5HP. The 1HP is rated 39GPM at 50 ft head, and the 1.5HP is rated 53GPM at 50 feet. These are both pretty close to the 1.5inch pipe max of 44GPM per minute, and well below the 80GPM max of the EC-75 filter. I guess I am just worried about breaking the pipes if the pump is too strong.
