Fuel pump woes....
Ok so I bought a new fuel pump for my '77 L48. I went with a Carter 120 GPH 5.5-7.5 PSI (as suggested by a forum member), it arrived yesterday. Well I went to install it today and only then did I realize that I had an extra line. Appearantly the stock pump had a fuel return line, and my new pump doesn't.... So can I just cap off the return line and still be safe?

1) The return is used to keep the fuel cooler by constantly recirculating the fuel back to the tank...cooler fuel is always better.
2) Keeps fuel pressure at bay and reduces the chance of premature part failure or wear on components by reducing unwanted pressure.
3) Too much pressure can cause the car to run rich the return eliminates this from happening.
I am sure there are a few more, but can't think of them right now.
