I'm purchasing an Airdog II 165 and plan on using 1/2" 316 stainless steel tubing to replace the blue Parker hose that comes in the kits. I've already spoken with Josh at Airdog regarding this but I want to hear clarification from another Airdog rep and maybe from those who are just as knowledgeable.
The 1/2" tubing I got actually yields closer to 3/8"-7/16" ID. When speaking with Josh, I asked if this would affect the pump's operation in any way or if it would somehow void the warranty with the pump. The short, quick response I got was just, "No." I had a VE pump custom built and the builder tells me that 3/8" should still supply more than plenty of fuel that is demanded by the pump and that 20-30psi of inlet pressure is recommended.
Referencing the following chart in the linked thread, if I were to run 25psi of inlet pressure, would this essentially make the 165 work more like a 108gph??
Flow ratings
This for a DF165
PSI ---- GPM
30 ----- 1.69
20 ----- 1.93
15 ----- 2.0
10 ----- 2.16
I also asked for the thread size in the pump base for the suction, supply and return lines. I was told, to quote Josh exactly, "1/2" NPT by 3/8" for both suction and supply and "3/8" NPT by 1/8" for the return line. I was hoping to get a thread pitch to be sure I get the correct fittings but I assume NP threads are pretty standardized. To be honest, the tone in Josh's monotone voice sounded like he wasn't too enthused about his job or even seemed like he was willing to answer any more than the questions I asked. I was quite displeased with this but I got answers nonetheless.
To sum up, I want to be 100% sure that there will not be a single issue with the pump. I'll warrant the tubing and fittings if a leak turns up somewhere, of course.
Feedback?
