updated spring for holley FP's?

[CollinsR]

I heard somewhere that you can replace a spring in your holley blue fuel pump to boost the PSI... . Is it true?



Thanks Guys!

I have run a Holley for a couple of years now and i just took the spring that was in it and stretched it about 3/4 of an inch longer and i got 16psi at idle and 9-10 WOT seems to be working for me.
