Injector and Seal Question:308QV

I just finished the major, cam seal, belt change job, and figured I have some time until the weather breaks so I'd like to change the injectors, they are still original to the car. The car is a US Spec 308QV, June 1984 build. I also recently changed every single hose, sleeve and vacuum line in the car, thanks to Dave Helms. The car now runs unbelievably great, I can't get over it.

Anyway, for anyone who changed their injectors already, I just want to confirm the injector is a Bosch #0437502047, right? These folks look to have the best prices around for these:

Also, it looks like there are two seals available for this injector (W0133-1642075 and W0133-1643510):

I haven't removed any of the injectors yet, and I won't until the new parts are in hand. So I'm unsure if I need both these seals, or only one of these? If one, which did you use?

Thanks in advance,
Phil

 

Correct

The Bosch PN for the "donut" seal is 3430210606 -- if you search at Autohauz on that part number it brings up two alternatives, but not the ones that you show . Those may still be OK, but I'm only sure about the Bosch PN.

 

Did my '83 QV several years ago. Your # is right. Found the Bosch injectors from a Mercedees Dealer for $5 each - was a phenomenal deal.
The donut seals where another thing. There seems to be two styles in use at the time. I pulled an inject out to find mine were the fat kind & I bought them from GT Car parts.
