I am in the middle of replacing all the rubber on my 85 spider. Now deep into the fuel injection rubber. All the posts on the bb here have been excellent help! I am now about to put new rubber gaskets and o-rings on injectors and discovered a difference from OE and am curious what others did. I could not find anything in the old posts that covered this. The OE large rubber gasket (#5 in the enclosed picture 1) has (a) an edge to accept and help center the flange (#4) and (b) is narrower and allows the Bob Seeger ring (#6) to seat in the channel. See picture 2 comparing OE vs new replacement. The overall width of flange/gasket/Seeger ring is 10.3mm (picture 3). The width of the new gasket (BECK/ARNLEY reduct from Rock Auto) + flange + Seeger ring is 12.3mm (picture 4). The new gasket also doesn't really seat well with the Seeger ring as it takes up the whole channel and you have to really work to seat the Seeger ring. The extra width and sloppiness of the flange leads me to believe the injector will not center and seat well into the engine port. Moreover, the extra width means the flange will be pushing the injector deeper into the port. What have others done? Can you get gaskets (part 5) like the original? Do you leave out the Seeger ring to bring the overall width down, but its still wider at 11.2mm (see last picture). Any insight would be appreciated.
