man, those new relays are very pricey. two questions: 1) does anyone here have a used, working one they'd like to sell? 2) secondly, i have read that one can use an 8v fuel pump relay in the 16v, but i don't know if i just need to make sure the pin pattern is the same, and that it's for a 4 cylinder - or is it quite a bit more complicated than that? thanks a lot, randy

FPRs have a rev limiter.

An 8v relay will not allow the 16v engine to rev all tehe way out.

thanks for your response neil. i never get close to revving my engine all the way out. i might hit 5200 on a reckless day, nothing more. so, does that mean i'd be ok running an 8v fpr in my car, or at least having that as a backup if i'm able to re-solder my original fpr? and would i need to make sure i get an 8v relay that has the identical 8-prong pattern as my 16v relay? thanks very much, randy

Why don't you use the full potential of the car? All the power is at the top of the rev band & if it's up to temp, has oil & water you won't hurt it. They're designed to be used & thrive on it.

Look on 190rev or mercedes190.co.uk for someone selling a proper 16v FPR.

Get a FPR from a Euro 16V.

Has the higher rev limit
