corvette fuel filter/regulator question
When I hook up my fuel pump on the inlet and turn it on it shoots the fuel out the return side and not to my fuel rail.The filter is brand new.I have the fuel set up as follows.3/8 fuel in 5/16 fuel return and single 3/8 on the other side of the filter going to the fuel rail.Could it be that the fuel line is full of air and causing fuel not to go through?

If you have the injectors/rails/lines etc all hooked up and turn on the pump for the first time, you'll pump just enough fuel in to bring the pressure up to 57psi. Most of the system will still be full of air until you bleed the air out. On mine, it didn't occur to me bleed the air out, so I just started cranking on it and it took a good 10 seconds or so of cranking for it to get any fuel to the injectors (then it started firing), and then another 10 seconds or so for it to smooth out.

fuel regulator
What year is your corvette and what regulator do you have in it? I just put an LS1 in my '96 camaro and I needed a '97 corvette fuel rail for my supply and return lines and I had the same problems i would only build 25 psi max after many cycles in my fuel rails and when the pump was done cycling it would bleed out the return side. I found out that the '97 corvette use a one of a kind fuel regulator so I bought it and pulled the '00 regulator out and my problem was fixed it will build 62 psi and hold it for hours after I the engine is off.
