difference between 1g and 2g fuel rail?

[WhyteSpyder]

I have a 2g and can not find any good bold on AFPR, so now I'm looking at Buschur Racing AFPR direct bold on a 1g rail. My question to you all is is there any difference in flow and size among the two fuel rail?

theres really very very slight difference in the inner rail size from 1g to 2g. 1g is a tad bigger.. and i mean a tad. like not noticeable to the eye.

the only other difference is the 1G fuel rail is shorter. allowing you to have more room for a direct bolt on fpr.

Mind you, the 90 fuel rails do NOT fit.. 91-94 works, 90 does NOT
