a quick fix ive tried is a tiny bit of the teflon tape under the needle orings, than a bit of oil or grease to screw them back in so they tighten up and seal again.. i use the smallest amount of gasket sealer on the crush washers that go in-between the fuel inlet banjo fitting... dont forget a zip tie around the slide boot... if it ok, than you know to get new rings and boot
ive had an engine come back to normal trying this after thinking i needed a front bearing..
