Fuel pump with carbs, Should it run all the time? Options

[brooks944]

Hi, I have a 1.8 ( now 1911) with 40 Webers and Web cam. It has run rich and my local shop has changed jets and it was running strong. I am now having starting problems and it seems to smell like it’s rich again. Last time I drove it it backfired a couple of times under load and it sounded like the backfire was from the carbs(?). My main question is on the fuel pump, which is a faucet type from the local auto parts store. Should the pump run continuously or shut off when a certain pressure is reached? Mine runs all the time when the key is on. I don’t believe there is a fuel pressure regulator on now.
Thanks for your help on my issues,
Rick

Please install any pressure guage onto a chassis point and not onto any engine mounting point.

the engine rocks... vibrates... moves around.

I've seen brass fuel line fittings work harden and crack when mounted onto the motor instead of the chassis.

helped put out a 911 engine fire at the track due to exactly this... cracked T fitting...

you don't want to mount to the motor assembly or anything supported by motor mounts....
