I ordered a new fpr diaphragm I was sent one for a v8 on accident. Will that still fit the one for my 90 3.1 or are they different ?

 

If you ever run into this type of situation again, here is a way you can verify for yourself whether it's gonna work or not......

I went to "Rock Auto" and looked up the FPR diaphragm for both the 1990 V6 and V8, and found them both to have identical part numbers.

So, since the exact same number is listed for both engines, it stands to reason that it will, in fact work
