Just something I notices while looking at the pictures, that's a huge a$$ inctercooler btw!
But it looks like you have a metal flex line going from your filter to the IP?
Can that be done with any size flex line?
That would sure be easier then working the that hard metal line that ALWAYS leaks!
Yes it is a stainless braid teflon line, there were some advantages working aroung the Helo co. at evergreen.!
There is also one from the transfer pump to filter.
Here are some pics of the 7.3 cooler cut down.
I dont think I have any installed, the in and outs are in a little different places between the two,
I went with it to uncover more of the condensor. I like my ac cold.
