Hello there
I trying to get hold of either original mounting rubbers NND6025AA and NND6025BA, or replacements
Any ideas where to find these?
Mine's had basically dissolved in my tank!!
And now, changing fuel pump, I can't find replacements!!
Any suggestions are welcome

 

your profile shows that your jaguar is 1999 xj8
The part numbers in your posting are for xk8 models.

please look at the xj8 fuel tank system diagram in the following ebay listing:

The part numbers NND6025AA and NND6025BA are correct for XJ8 NA and also SC and appear to be used in the XK-s as well. Both parts are NLA so one has to look for replacements (not exactly the same as Jaguar parts) from aftermarket pump kits.

 

try contacting Jaguar Reno | 9150 S Virginia St Reno, NV 89511 | (775) 332-4003
https://parts.jaguarreno.com/oem-par...ting-nnd6025ba

they show both these parts (does not say anything about being no longer available)
