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

Thanks all. Porschetub, I ordered the one you recommended. Do you have a picture where you mounted yours?

Most by the steering rack or under the tank. I put mine more up front for easy access under a modified fuel tank. Should be in the push position. Best, mark

I did the same thing with an off cut of copper nickel line! Except mine is under the fuel tank.

I got tired of the under tank lines kinking. That 180 degree bend from the pump to the tunnel was always kinking. Fixed it easy peasy by making a hardline for that bend.
