It's most likely leaking from a bad hose, not the pump itself. The pumps CAN 
develop leaks, but not big ones.

Yes, the hoses down there last much longer than those in back because things 
never get hot under the front end, but they still need to be replaced

DON'T do that. The filter traps dirt (and water, in small amounts) and keeps 
them out of the pump. You lose this protection if you move the filter to the 
rear. PLUS, our filter is a low pressure filter and it not made to stand up to 
the 30 psi side. It might work, but I wouldn't want you to take that chance. I 
think the most likely outcome would be that it would seem just fine now, but 
would fail on you some really hot day. We don't want to think about the 

You could add a high pressure filter in the rear and leave the OE filter in the 
front, but I don't think that enhances anything except complexity.
