It’s continuous use only. I don’t know if you saw the video I posted on this Facet pump I installed.

Yes i spotted the return to tank pipe in the workshop manual you recommended, im thinking this is why my frankenpump doesnt shut off, basically because it never gets that back pressure to shit off.
My car is an sz, 03614 to be exact, its a very early spirit.
I will look again at getting it started and only then will i know if the pumps work, they are noisy though so not ideal.

If your system came with the vain pump, then you do not want the fuel pump shutting off it must run continuously.

What about the ticking noise though?

Freudian slip with the "shit off" in my previous post haha, obviously meant "shut off".

Remember, you can correct these by hitting the "triple dot" menu button at the top right side of any one of your own posts and choosing "Edit."

result of the new fuel pump

You have the wrong clamps on the fuel hose. Fuel hose clamps are rather tight and therefore they dig into the hose with the worm gear. The correct hose clamp is banded, usually a rolled edge, with a nut & bolt design common to fuel clamps. BTW..the rolled edge is designed to not dig into the rubber hose when tightened.

Yes, I just put those on there so that I coild test the pump as I was out of the proper clamps and was waiting for Amazon to deliver new. I didn’t want to go full bore install until I knew it was going to work on the car. This was the fourth pump. I’ve installed in two weeks trying to find a proper pump.

The one thing that concerns me about this pump is it is a push pump or gravity fed as they say. The outlet of the gas tank on this car is quite high. I’m not sure if that’s going to be an issue or not as I have only taken the car at once. My headlight issue has reared its head again which I wrote here about in 2018 so I’m trying to put a permanent fix on that before I take the car out again.

Final implementation

Nice work.Michael. If you notice on your SL, the Bosch FP usually has a cushion sleeve around it plus the bracket has the studded rubber isolators, all design to quiet things down and isolate vibration. I have a 1972 350SL
