I got it done last night. I trned the key and once I found the fitting I didnt tighten, it seemed to work just fine.
The injector return line. I flaired it and put a 3- -4 union on it and ran it to the return line.
The return line. I took the line that went from the filter to the pump and flaired one end to -6 and bent it a little to make it fit.
The supply lines are -8 teflon hose (nitrous line), and the return is made from -6 AQP rubber line that I recycled from the last time I plumbed it.
The pump is a Shurflo 2088-313-145 diaphragm sprayer pump. It came with rubber isolators for the bolts, but it goes from loud to really loud when it gets pressure. But when the truck is running, it aint noticeable.
The filters. Did you know that a 1" 12 thread filter mound will take a 1"14 thread filter.
It dont leak so it will work for now.
