Need to cap fo factory fuel supply line

[JJKPowerstroke]

Hello all, I Recently finished my Airdog 100 install on my truck. It's a 98.5 24v.
I have some fuel coming out of the factory line. back at the end of the factory line at the tank. Could I be pulling a vacuum threw it. I have the fuel pump on the engine block and have the banjo bolt and supply line off of that going to the fuel cannister. I went with the Vulcan big line kit so I can still use the fuel heater. Where can I get some caps for the line.

Thanks,

John

you just need to get a dorman fitting to cap the line at the tank. NAPA should have them
