I have mine wired to come on under boost.

A Hobbs Switch and Relay energizes the 2nd pump when the engine is no longer at vacuum.

I'd think two pumps running all the time wears one unneccesarily AND heats the fuel more.

More pressure through the lines all the time, too.

Do you have any pics how you installed a second Walbro on a 99+ tank? Very curious to see this.

Here is a pic of a dual Walbro 340 setup. One pump is fulltime and the other is set for boost application. This is for a 800+ horsepower Supra, but the idea is the same.


Click the link in my sig if you want to see more pics. I will work on the shop owner to put a dual package together for the LS1. He is quite clever with this sort of thing.
