I also installed a small pad under it to attempt a degree vibration reduction that it "feels".
I've mostly seen the contact failures (any of them), especially the fuel pump contacts. I've often wondered about an aging DME relay causing strange happenings, other than an outright failure. Although I've never tested this scenario, I often wondered about voltage drops occuring across the contacts (as it slowly becomes resistive) , resulting in less voltage to the fuel pump,..then what? Again, just curious about this impact on the fuel pump (proper) operation...Guess I'd have to look at the fuel pump specs to truly assess the "what-ifs"..
The other failure I've found (on a friend's relay) was solder fracture on the coil connection at the PC board,..resolder fixed that.
Again, I changed them out cyclically (preventatively)...never been a fan of any resistance in any contacts on any relays!!!!!!!!!!!!!!
BEST!
