Well, You'll be glad you took the leap. The pingle is
so much easier to operate, delivers great fuel flow, looks nicer, allows you to run the fuel down to almost dry on reserve, plus in my case anyways, no starvation and factory like fuel performance as far as the light and draw. (
with factory petcock and pumpless I used to run out of fuel at 1.5 gallons, could not drain off reserve and the low fuel light never came on.)
And it's so easy to turn off and on!
I thought the Pingle and high flow fuel filter was less duckies at Maxair, I could be wrong.
Anyways. I took old one off, turned tank up side down, Put the pingle plate on, marked hole with a Perm Marker, flipped tank back over. Got under it with a rat tail file in a drill and a powerful magnet stuck to it, Then I flied the hole out that way, it went quick. I then washed any leftover shavings out with a good blast of
carb cleaner. Makcap thinks I cheated.

He was like what? your done already?
Oh! Important! The gasket they give you is too large and it's blue and looks like CRAP if you leave it. After you get the hole the right size to a dry install and run the Perm marker around the plate to indicate where to cut the gasket before you add glue and install. I also suggest you color the edges black with the marker for a neater install.
The directions with the pingle are fairly lacking. Be sure the surfaces are very clean, let the adhesive set the required time on both surfaces. (They give you plenty, I had 50% left over)
Evenly crank your bolts down.
Have fun!
