I have at last installed the Airtex and will use it as a primer.
After sitting for some weeks, how long should I keep the button pushed before trying to fire the engine?

Till you get bored. Listen to the pump, it will run fast then slow down and virtually stop when the carb bowls are full.

Hi Al.
The Piersburg pump was installed 10 years ago and run as the only pump. I bypassed the mechanical pump.
Upon disassembly I found the Piersburg to have power but would not pump. The Airtex pumped usng the existing wiring.
The new installation is set up to work as a primer pump and not to run all of the time. It is about double the size of the Piersburg which I hope means greater volume.
I think either pump would by just fine as a primer.
No worries here,
Greg

I can now offer this assessment of the project.

The entire system operates far more efficiently if attention is paid to where the fuel comes from and not just where you want it to go. This advice is the result of several hours of methodical trouble shooting and true Sherlock Holmes style deduction.

I got the pump in backwards blowinig bubbles into the tank instead of feeding the fuel pump at the rear.

Duh...
Greg

Greg, I just had exactly this problem with a brand new Carter fuel pump in a replica spider. Difference in my case was that it was connected up correctly with the OUT port connected to the pressure regulator and thence to the carbs. Same issue, air blowing in to the tank and when I put my finger over the out line it sucked my finger in. It was just one of those days though. It was a 15 minute job that eventually consumed 4 hours with 4 runs to the parts store and one to Walmart.
I guess it makes up for those days when everything goes boringly smoothly.

I recently just installed the Airtex fuel pump. It was easy peasy. I just had to pickup a length of 5/16" fuel hose, and two additional 90 degree angle fittings and a length of 14 awg wire. I also added an inline fuse holder with a 10amp blade type fuse.
I bolted the unit to the diagonal member where there was already an existing hole.
I already had a spare GM (momentary) rear trunk release button that fit in the area for the sunroof switch. The little pump works like a champ. I'm pleased.
