Check valve

Should a '76 911 2.7 have a fuel check valve at the fuel pump outlet? Thanks!

I recall, the 76 has the pump in the left rear. The banjo that connects there is the check valve.
911 356 066 04 is the hose, the check valve is in the banjo next to the pump
I have purchased the check valve by it self

Same as above. Some pumps have a check valve on them, others use a separate check valve. Whichever, you should have a check valve somewhere between the pump and your CIS.
