I have a B&M FPR that I'd like to install soon but it's missing the extra spring that comes with the B&M kit. I'd like to know if it would be possible for me to reuse the "stock" fpr spring in the B&M fpr. Are the springs the same size, and swappable? Or should i just call up B&M and have them send me a replacement?

TIA for the knowlege, Neil

 

Same thing happened to me, and I posted trying to figure it out on here, but noone replied.

I know the spring w/ the afpr is either shorter or longer than the stocker, so it can be adjusted to higher fuel pressures.

for a good question!
