I notice the Edelbrock adjustable fuel pressure regulator comes in 2 varities. One with a "-6 AN inlet" and one with a "-10 AN inlet", what do they mean and which one is right for a 355, stock fuel pump, 22 or 24# injectors?

Thanks......

Up to you 3/8", or 5/8" tubing, stock is 3/8". The 5/8" tubing wil need more pressure to maintain the proper spray pattern.
24#s will do.

The number in the size 6-AN is the denominator of a fraction with a numerator of 16 representing fractional tube sizes.

2-AN=2/16"=1/8"
3-AN=3/16"
4-AN=4/16"=1/4"
5-AN=5/16"
6-AN=6/16"=3/8"
8-AN=8/16"=1/2"
10-AN=10/16"=5/8"
12-AN=12/16"=3/4"
14-AN=14/16"=7/8"
16-AN=16/16"=1"
20-AN=20/16"=1-4/16"=1-1/4"
24-AN=24/16"=18/16"=1-1/2"
32-AN=32/16"=2"

 

i always wondered what those measurements where. thanks.

 

BTW AN means Army/Navy
