Thanks, that did help on a skymaster F15 I was having a hard time getting max rpm with.

This UAT I have never had before, it has a huge 8 size nipples on pump and suction side, instead of putting the 8-6 adapter so close to the UAT I will put size 8 line to the tank, then put the adapter.

Its crazy to me, I have a AMT 450 at 48 pounds of thrust just using plane 4 size line with no issues, but it dose have a huge pump!
