How much vacuum hose for single-turbo FD?
 

If I wanted to replace the vacuum hose on a single turbo FD, roughly how much vacuum hose and in what sizes should I buy?

That totally depends on your setup. My car has 3 vacuum lines (MAP, fuel pressure regulator, recirc valve). YMMV

Lol. Why cant you just do a stock take on what needs replacing in there?

Didn't have to time to do it before leaving the country.

Ok, fair enough. From memory on mine there's the wastegates, the bov, the fpr and the brake booster. [edit; and MAP reference]. I used 1/4" fuel hose because its tougher. The brake booster is a bigger size though. And heat sleeves on anything remotely near hot exhaust bits. Also of lesser importance the charcoal canister hoses.
But its all stuff (except maybe the sleeves) that you can get at local auto-parts store so probably easier to wait till you are there.
BUT, because i've seen your other thread, if it was me, I'd be going over that whole car and be prepared to change out all fuel hoses, along with probably cleaning every electrical contact and ground connection and a million other things.

So I shook buy some 3/8" push lock EFI-rated fuel hose? How many feet?

hey bro, when you coming back to BAMA?

bumping this thread because it still never answered how much do you vacuum need about for a single turbo,, iv searched and saw for twins but not single.. dont want to order like 10 extra feet if i dont need it

FPR to UIM, MAP to UIM, BOV to UIM, wastegate to controller, controller to UIM. At leaste on mine, maybe 11 ft or so to keep away from exhaust.

I just bought 25ft of 3.5mm silicone vacuum line from boostcontroller.com. I think it was .89 cents a foot.
Better to have too much than too little. You always have extra for adding something that needs a manifold pressure reference.
Also pick up some brass T's so you don't have the plastic ones fail on you and cost you a motor.

so i will only need about 15-20 feet of just 3.5 and thats it or i think i saw in another thread daleclark saying also need about 10ft of 6mm or 8mm, not sure if i also need that for single since i think he was talking about twins
