It's not in the right kick panel - check behind the glove box by removing the cover under it.
Remove the glove box. Two or three fasteners and you get best access.
They're both wrong. Remove the passenger side fender and sneak up on it from behind. It'll never know what hit it.
I really appreciate the help. So far I have removed the whole right side of my 81 380sl and have stumbled on several relays behind the glove box. Some are silver others are black and even a nice anodized red one. is there one tell tale give away description or a pic for the fuel pump relay???

Although I never really confirmed the fact that it was the fuel pump relay, the only relay I found that resembled it was below the steering column,,,,,

OK, since my dash is still partly disassembled. I'm going back in to confirm whether or not the 76 450SL even has a FPR and if so where is it!

I'm tellin ya, the only relay that looks like the one posted as the FPR is near the steering column. Unless it is one of the silver /tin types.

Here's an interesting one. 380sl 1985. Car starts and idles decent but get hick ups no matter if cold or warm. the fuel pump cuts out frequently for about a second and hear sometimes a clicking sound by the passenger footwell. My question is... If the relay was bad wouldn't the pump just die and engine stop. can a relay disconnect and engage again after a second or spit second? Has anyone heard such a thing?

A weak relay can fail intermittently. Find the clicking and replace that relay.

Maybe this can help you, right behind the glove box. Small rectangular cube black in color... From my 1982 380 SL

My way of thinking, if you hear the relay clicking, it's not the relay. It would be something that controls the relay.
