Hey guys I'm getting ready to install a 392 pump system on the truck and was wondering if anyone has tried to use the rear tank fitting, the one that many of us have put filters on, as the return instead of using the supplied return manifold. The weather is nasty and raining out right now so I haven't checked if it is a one way checkvalve fitting or anything and thought I would run it by you guys first.

 

I just ran mine back to the fill neck with the supplied tee. Its easy to tell now when the system is primed, just walk to the fill and you'll hear it draining.

 

You have two lines coming from the fuel tank. The supply line 3/8 and the return 5/16. You need two tees to install the pressure regulator. one tee pressure side of pump to regulator to the second tee going to the return line.

 

I hear ya guys, I was just wondering if I could hook to the rear tank fitting that I put a hose and filter on to keep dirt from getting into the tank.

I'm just trying to keep from hacking up as much stuff as possible and use what is already there.

 

You mean those tiny little breather fittings? They aren't NEARLY big enough for return fuel. I used the supplied fill-hose "T", but if you do the vent mod at the same time you can use the stock vent.
