I am having mine made locally, we (Coast Guard) have all out 3 4 and 6 inch lines built by them so there hooking me up. I dident want to deal with building my own so i am just gonna pay they to build complete lines. I ordered my pump off line ebay E3270 Airtex for about 25 dollars. But I just learned there is a in line pump that will work. umm here Walbro makes a 255lph inline pump. that might be an easyer way to go. I think i might buy one just to have it.
