Fuel Return Line from rail keeps on coming off

    Hello guys

    I've been having a problem with my car for a week or so. The hose that comes from the fuel rail to the return line keeps on loosing or coming off. No matter if I push it back in, it will come off again. The car sometimes struggles at high rpms either in full throttle or part throttle. Sometimes when I come to a stop it will just shut off. I'm guessing that this line coming off might be the problem, but I'm also suspecting that the fuel pump might be running out its life. Car scan shows nothing.

    What would be the best thing to do in this case? Buy the new pair of hoses? (They go for around 250$ from ecs tuning). I'm planing also on making some tests with the local shop to rule out the fuel pump.

    Any insight would be appreciated.

    Shouldn’t there be a clamp on the hose like the one beside it? I’d try that before spending $250 on a new hose
