I chose to buy the part from the dealer (came with the o-rings)>$240. It seems I was having tomato, tomatoe part name callings. The EHA is the 'Fuel distributor governor' and many more names to go along with it. As all has posted it is a very easy removal/install but I do suggest wrapping it in a paper/shop towel before removal, fuel did soak mine within seconds, eye cover without, thanks for the website!
