I am sure this is a popular topic! I need to replace mine soon and am
thinking of doing it myself as all the quotes are really high. I could
spend twice the time (six hours?) and save hundreds...

I did find a place to buy them online (one of the Vanagon places) but I am
wondering if there is  "laymens" guide to switching them out which
might
include a list of tools! I do have a full tool set but don't want to be
caught off guard.

Seattle area - Eastside - if it matters...

I did just get back from Wolfsburg Motor Works in Ballard where they fixed
an exaust leak and did a few other great things related to fuel pressure.

Thanks,

Andree
