How do go about installing fuel system?

You need to find out if that canister is recommended for "suction" use. ANY filter before a pump, IE on the suction side, must be very free flowing and have LOW pressure drop

The only advise I have about the sender is,

Make sure you have a new gasket, inspect the new retainer ring against your old one and use the heavier/ better made one if there is a difference. Don't overtighten, and LEAK test the thing. Since you have the tank out now, you can put a few gallons in, and tip it forward with the appropriate fittings plugged off to test.

Also, now would be a good time to SERIOUSLY consider a "vapor return" system. If you don't have return port type pressure regulator, you can use a Wix filter (others make 'em) which has a built in 1/4" return port. This needs to get routed back to the tank, so RIGHT NOW would be an excellent time to get a two port sender if you don't have one, or silver-braze a fitting into the tank for that purpose

THESE WORK!! First time I ever saw one was on my 70 440 sixpack RR, which was factory on the sixpack and hemi cars.

Wix 33040, 41 for 5/16 and 3/8 lines respectively
