Looking for advice on replacing fuel injection rail on spider 2000 1980. Can it be done without removing the intake manifold? I am having trouble getting the rear injector to seal in the injector port, it is not misaligned but will not bottom out on the intake. Any help would be appreciated

Update I have installed the rebuilt fuel rail to the intake without too much trouble, but believe I have a leak on #4 injector and the cylinder is getting air through the seal. Any suggestions I had the injectors and fuel rail rebuilt could the improper length of the hoses on the injectors to the fuel rail prevent me from proper securing to the injector ports?

Got it done and is working well secret was the retainer clamps being put back on the injector after rebuild, they were put on backwards and would not press down far enough on outer rubber to press injector far enough into injector port on intake manifold
