Danny P Posted January 10, 2017 Share Posted January 10, 2017 The corks of the main petrol tap from my bedford MW need to be replaced. Does anybody know the exact diameter and how to make new ones myself? Or would there be a better alternative like rubber? Thanks, Danny Quote Link to comment Share on other sites More sharing options...
Ron Posted January 10, 2017 Share Posted January 10, 2017 Probably easier to just buy some off ebay. Sometimes the stem unscrews from the knurled button and sometimes you have to punch it out with a nail and gently peen the end after it's reassembled. http://www.ebay.co.uk/sch/i.html?_from=R40&_trksid=p2051541.m570.l1313.TR0.TRC0.H0.Xfuel+tap+corks.TRS0&_nkw=fuel+tap+corks&_sacat=9800 Ron Quote Link to comment Share on other sites More sharing options...
rampant rivet Posted January 10, 2017 Share Posted January 10, 2017 As Ron has just mentioned I found some on eBay that did ok don't forget to order extras in case you have trouble with them later on, oh and be carefull trying to unscrew the rod as they are liable to snap I speak from bitter experience 😣 Quote Link to comment Share on other sites More sharing options...
Danny P Posted January 10, 2017 Author Share Posted January 10, 2017 Thank you Ron and Jeremy! What diameter do I need. Do I need a certain oversize, soak them in water to soften and fit? Quote Link to comment Share on other sites More sharing options...
rampant rivet Posted January 10, 2017 Share Posted January 10, 2017 I think it's best to measure the bore of your tap and allow the corks to be a tight but no too tight a fit, I think the ones I bought were oversize and reduced their dia by fitting them onto a spindle and sanding them down to fit, not sure about using water tor soften them I used WD 40, Best to make sure the inside bore is clean too. Because the petrol pump is pulling the fuel from the tanks if joints etc are not tight it will allow air in causing trouble, and lastly when you come to fit the petrol tap it's best to make sure that the petrol pipes are fitted correctly or again you may struggle to get the fuel up to the carb.

Ron Posted January 10, 2017 Share Posted January 10, 2017 Well I think there are usually only about 2 sizes for the plunger type taps. Check yours and compare with what's for sale. I often have to replace leaking corks in my motorcycle taps Some are the plunger type and some are the ENOTS with a flat slide between two corks. I just buy up the different sizes for my stock at motorcycle jumbles. I usually let them soak in engine oil for a while, which also lubricates them for the first few on-offs. Another problem I've encountered with the slide type tap, is the slide can shave little slivers off a new cork and deposit them in your main jet.....Another good reason to oil them.
