The pump installed has 384h of good work until now.
My doubt was regarding its capacity to deliver the necessary amount of fuel to permit flying at cruise power.
I´ll check the pump part number to verify.
The old pumps just had weep holes on the flange.The new pump can and sometimes weeps a drop of fluid or two. That is normal and not a sign the pump is bad.

The pump is installed in the upper part of the engine, above the exhaust manifold pipes.
Any fuel drops that may come from the vent line will drop to the cowl near the exhaust , what is in your experience the better way to deal with this?
I´m thinking to make a small hole on the cowl and put the tube coming from the pump through it so any fuel will be released to the atmosphere avoiding any contact with the exhaust pipes. The only doubt is if the velocity of the wind at that point is not going to cause a kind of suction that could be harmful to the good operation of the pump.
For example on the RV-12, the engine-driven fuel pump drain/vent outlet is plumbed back under the right-side cylinders back to the firewall and down to a neutral pressure area near the lower edge of the firewall (adjacent to the oil tank vent tube). The end of the these two tubes should not be subject to dynamic pressure or vacuum.
