hey i have a 95 5.0, i was wondering what vacum lines you guys are using to suck in the seafoam? Ive heard brake booster and pcv. The vacum tree on the drivers side of he engine bay, which one of those lines is the brake booster line? anyone have a picture? would it be better to suck it in, in spirts rather then just one chug so it has less chance to hydro? Any advice is appriciated thanks, Jay.

use the one that goes to the intake manifold

adder i took a picture, this is the line that goes from the vaccum tree to the intake manifold. Is this the one you are talking about? I beleive it was labled "S" on the vacum tree, and its the lowest line which runs straight to the intake manifold and FPR the second picture is of the brake booster line. Just let me know which one

also should i just let it suck it all in at once, or let it take it in in spirts? Will it stall out or do i turn it off after its all done? Let it sit for 15 mins then start up again? Adder i know i ask alot of questions but you always have the answers i need. By the way i took your advice and just put the regular dexron3 in the tranny, and much smoother shifting has been received! thanks once again guys, Jay.

It would be better to use the small line off the fpr. you want to slowly let the seafoam into the motor. if you add it too fast, you can hydrolock the engine... and thats bad

i use transmission fluid
plus it pisses a lot of people off

adder i did it through the fuel pressure reg vacuum line like you said. waited about 20 mins started it back up and nothing. started revving it up and got some smoke but definatelly not like the videos on you tube. Did i do something wrong or is my motor relatively clean at 90,000?

possibly, every engine is different, have you noticed a smoother engine operation?

it really doesnt seem any different to be honest. i took it out and ran it WOT 2-3 and really no difference.
