Install home heating oil line filter

Hi all,
I bought a home heating oil tank in line fuel filter. Im tired of changing my nozzle once or twice a winter and cleaning my small pump filter then have to prime. Cant be good to have to keep taking it apart.
Anyway, I have my tank out back, its a trailer.the supply line is small copper line in the dirt to the house. Maybe 20 feet lin length. I'd like to install a filter right off the hardline right after the tank shutoff valve. I dont have welding skills but I've changed transmission and radiator hoses etc.
can I use flexible hoses with clamps to install the filter.

I dont see a problem with it minus insurance qualms or maybe state law or codes requiring hard line. I dont have much clearance from the supply line to the ground if any so this would also facilitate that issue rather then having to figure how to raise that line or dig a hole for a box to hold filter. I dunno. I figure if I secure everything tightly it will be fine and put it in an aerated box above ground.
So in your answer other than law or insurance issues, is there mechanical issues if I use fuel rated hoses? Short hardlines from inlet and outlet to the hoses since those are female and to make a males connector for the hose.
thank you

Welcome to the forums.

I'm not the boiler or oil pro but I'd rather see the filter inside close to the boiler in a heated area.

Typically the filter is installed inline using flare fittings as they are the most reliable and air tight.
Rubber line connects shown as well as compression type fittings.
Compression fittings are good when the oil tank is above the burner as they are not always
100% air tight and can cause priming issues.
