    I just picked up two saws. Both husqvarnas ones a 142 and the other a 41. Both need new fuel lines as they are broken off inside the tank. What size line is this? I have searched but can’t seem to find it.

    Thanks

    Probably 3/32 ID x 3/16 OD. I don't think they used tiny .08" x .14" on the Poulvarnas...but if they did, drill fuel tank hole with 11/64 bit.

    Yeah it’s the smaller line. Found a piece in the ones tank and it was written on the size.

    So if I drill it out it will fit the bigger line and still fit snug on the carb

    Yes , it will be a good repair . Makes a snug fit in the 11/64 hole and a good fit on the carb .

    Keep in mind, the line should fit the hole tight enough to seal but not so tight that it restricts fuel flow. I just had this problem with two Husky 128LD trimmers. Both ran great for a 4-5 seconds at WOT, then bogged down. Drilling the tank hole larger corrected both.

    Adding to good advice above....Pulling line through hole should be a LITTLE hard but not REAL hard.

    Thanks. Didn’t know making it slightly bigger was a possibility. Also what’s a good cheap fuel filter for these? I’m going to order some today as soon as I get the chance.

    Electrical grommets can accommodate too large a hole and a smaller diameter fuel line. You can find ones in a multipack and pick one with the tightest fit for your size fuel line. They seal fairly well too

    I cut the first inch or so on an angle to get it started more easily

    If it’s a real doozy, you can use plumbers grease.

    Yeah I’ve used a little oil in the past or get it through. Just had no idea of the size as there was no lines on it It took me awhile to even find were it went into the tank.
