Hey guys
I have a 77 f150 w/400 and there is a vacuum tree on the rear of the engine. The lines go to my tranny, brake booster, and some other things I dont remember. I have tightened it with a wrench but it keeps coming loose. How can i keep it tight?
Thanks
David
I dont know about the color cause its covered in grime but its on the back of the engine or intake manifold and yes they all face the same direction.
Thanks
