    Both of the Fuel Accumulators on my 90 TR are leaking (pretty easy to find this one!) weird they both started at the same time. ON my parts list, it is part 125135.. I can see that on the list here so others have this issue too.

    Anyway, the Passenger side has BOSCH 0438170042; the one on the Driver side has NO number stamped on it.

    Looking at one site, they mention 0438170001 as the replacement for the 125135, which is the part autohausaz.com (They are great by the way) has and I have ordered.

    Can't seem to see if the 0001 is the same as the 0042 or would work, they look the same ...
    Anyone know? BOSCH isn't much help....

    I believe either would be OK as the shut-off residual fuel pressure spec is the same for F models using 0438170001 (F PN 113978) and 0438170042 (F PN 125135) -- assuming the fitting sizes are the same and the body size fits the clamp (they look it, but not 100% sure). The weird thing is I know 0438170001 to be the style with the 90 deg vent nipple on the end like this:

    but the picture that Autohausaz has for 0438170001 is this:

    which looks very similar to 0438170042 (no vent nipple and the small screw at the back end). In fact, if you do a search on ebay using 0438170001 you get a bunch of slightly different styles -- can't explain it, but it seems you can get something that looks a lot closer 0438170042 even if they call it 0438170001 (maybe getting 0438170001 with the 90 deg vent nipple is now the unobtainium ;)).
