I am afraid we have been unable to get these for some time now. We recommend the following taps.
65-8171 – This tap is the same thread type but just a different lever style, turn type rather than push pull.
29-7764A – This is the same top thread however is a push on fit for the fuel pipe. We also do worm drive clips to hold the pipe on.
27-8552A is the same style as 27-8552 but the bottom thread is larger so you will need our 14/042 and 14/026 parts to convert.
