Hello, I believe we actually responded through email last month, but here's a rehash. The spigots that we supply with those inlets are 3/8", and the holes in the inlet are 5/16", so they should be tight and not leak.
You should double check also that the 3/8" side is in the inlet, if it's the 5/16" side, then it could cause a leak.
If you wiggle them around when it's under pressure, it might leak some, but normally when driving, it would not leak, since that area is under vacuum.
If you need new spigots, let us know.
