What is the Ac Delco part number for the GM relay 14078907. I can't find it on the AC Delco Web Page because i am not a member...well i gess.

That number supercedes to a GM# 10094701 and the delco number is 212-305

That's why the dealer told me this morning that part number (14078907) was no more available

Thanks!

i JUST replaced this (is it ur fuel pump relay?) go to autozone/checker or any parts store. then have them give them that #, 14078907 , and tell them to cross reference it. if u can, take ur old 1 with u (dont let them use its #) cause the 1 in their book 4 our car is is like oval but the 1 we need is square.

yeah, the original number on the relay is what they sometimes call an "engineering" number, and the service part number is different. it took me about 5 seconds at work to figure out the right number (i work at a GM dealership in parts)

O.K. now the good part because the ACDelco relay is no more available (GM Dealer), I bougt the Standard or Bleu Streak (same part number) RY-121 it replace application GM part with O.E.M number 10094701.

Everything work fine now

The only thing I’m confused with is the fact that some application use this relay for the fuel pump and sometimes other application and in my application it is use for the electric radiator fan

The person at the GM dealer gave me the part number 14078902 ACDelco p/n 15-8218 for the V8 Camaro radiator fan, it's a 4 connector relay and the one i have O.E.M 10094701 is 5 connector.

Thank you all!

i am having the same problem , mine is a 5 pin connector and all i can find is a 4 pin but i did have a guy with a G M refference book check it for me on the weekend at a big automotive fleamarket and he says the blue streak # RY121 should replace the old 14078907 the extra pin is a extra ground wire ... going to buy this relay this week
