Default bad leak in f-hose area, but it isnt the f-hose.?

I did a pressure test, and I am getting a pretty large leak from the area of the fhose. My car already has the "home depot" f-hose, so im 99% sure thats not it.

What I am worried about is that its those plastic lines going under the manifold. What could it be since there are only three sources where a leak could exist, unless it is something else very close to the fhose.
Does anyone have a link to replacing that plastic hose under the manifold? I remember seeing pictures somewhere. that might help me.

thanks, chris

Default FYI, I had a leak with my Home Depot F-hose - it obviously was not on part of the F-hose itself.....

since it's now metal, but where one of the "fingers" went into the stock hoses. It was leaking at that insertion point.

Anyway, I planned to go with an MTM F-pipe anyway and was using the Home Depot mod since it was the only place open when I broke my stock F-hose....once I was getting some goofy boost behavior I checked everything and found the leak. I had already ordered the f-pipe but had not installed it - installed it and the problem was gone.

Default what about the corrugated black tubing that always breaks leading to it?

this is probably what it is, and now I will need a new one. Does anyone have the part numbers? How hard will it be to replace?

Default I had to replace mine. It's a PITA and it cost ~ $80.

Do a search on "corrugated hose" and "spider hose".

Default PaJohn, I'll let you in on something...

The main leak, I found out to be my main hose to the throttle body. When I say main hose, I mean the one I use for my FMIC! I just completed a similar setup to blitz's, but bigger, and better.

I overtightened the 3/4" wide clamps, and it left a portion of the hose unsealed. Anyways, I fixed the big leaks, which than uncovered miniscule ones. Soon enough I will have them all solved, and be hearing a lovely bubbling sound without any hisses. : )

thanks for your help on the "spider" hose; which could still have a small leak in it, but I doubt it. Here is a little teaser, just for you. : /
shhhh!
