    Hi all, I need to replace my fuel hose and having issues removing the banjo bolt on the fuel pump. I'm guessing this is a normal clockwise thread? Are they usually stubborn to undo? I cannot move it at all with a hex socket, locking pliers etc as now rounded off! 😩😩😡😡

    Oh dear, yes it is a 'normal' right handed thread (tightens clockwise or righty tighty, lefty loosey if you prefer) why would it be anything else?

    What happens here is the bolt, sealing washers and banjo can suffer from galling and become cold welded together. Assuming you're allowed spanners first off I'd prepare the bolt by giving it a goodly soak in penetrating oil, then heat it using a soldering iron (the idea here is for the heat to transfer down the threads) then tap the bolt head with a drift to jolt the threads and if accessible tap the sealing washers sideways to break their seal, followed by a second soaking in penetrating oil and allow time to penetrate.

    After prepping the bolt the options include: use a centre punch as a drift on the edge of the bolt head to get it moving; if that fails try the same with a small sharp cold chisel; if that fails cut a slot to provide a snug fit for an 8 mm flat blade screwdriver; lastly grind the head flat, drill a pilot hole and remove with an easy out or extractor.

    This is not a job to go monkey boy at, if you're not allowed spanners seek help from a competent person who is.

    Top tip - Check your tools regularly, especially Allen drivers and cross point screwdrivers, replacing any that show the slightest sign of wear.

    Whoops, that should have read 'tap the banjo sideways (lefty loosey) to break the sealing washers seal'

    Hi, thanks for the advise i will give it a go over the weekend. I have soaked it for the last few days with WD40 to help.
