I've got to redo all the vacuum lines on my car since I've changed to an SMIC (that and most my lines are the OEM ones that the car rolled out of the factory with).

I'm thinking of using push to connect fittings as they would be a lot neater and the price difference isn't bad. Anyone else using them?

All I need them for is my AFPR, BOV and wastegate/turbo/boost control set up. Only other vacuum line is the brake booster and that would stay rubber.

I am also curious about this as well. I don't have as many vacuum lines as you do but eventually I will.

I went with 4an stainless on mine, but its expensive. Just for the bov and wg I had to get 4 fittings and about 5ft of line, and it cost around $50 give or take. The plus side is they will not have vac leaks .

I use the one touch pneumatic fittings for everything under my engine bay that I can. It works really nicely and the hose is much cheaper than AN braided stuff. They even make metal ones that I attached onto my wastegates so I don't have to continually drop the reference line inner banjo washer on the floor .

Do you have a link for where to buy them?

I ran my meth system, BOV, AFPR, etc. with these fittings.

Thanks landspeed. Is the hose on their site the hose you use? It seems like the hose is for barb fittings.

I just did this on my 1g. I ordered everything from McMaster. This is what I got:

5112K53 - nylon tubing 1/4" OD
5779K108 - 1/4" OD 1/8" npt straight fitting
5779K44 - 1/4" tube wye fitting

The 90 degree swivel fitting for 1/4" tube and 1/8"npt is 5779K151 if you need those.

I tried to add a fitting to the smaller port on my intake manifold, but could only get 1/8" tube od for the 1/16" npt that the thread matched up with. After looking at how small the small the ID of that tube was, I scratched that idea and went back to silicone hose for that one fitting.

Hope that helps.

Any photos?? Would really like to see this.....

5097t41 comes in different colors too : )

u recently did a vacuum block setup and all stainless -an lines. Cost was well over $500.

I've ordered a lot of push-to-connect fittings from MettleAir on eBay. They have much better prices than McMaster and Amazon. Just go to their store front and you can sort to what you want quick and easy.

This is where I got mine. I've got maybe $100 into the whole set up.
Time will tell what the quality is like though.

I know it's only been a couple of months, but any reports on the quality of the ones from eBay? Has anyone asked what the ID of the hoses he offers are, if you are using the hose from him as well?

Edit: I see some of the 3/8" OD hoses labeled to show a 1/4" ID.

Also, do those fittings swivel (to allow a few 90° fittings to be installed next to each other)?

All my fittings are from Metle Air on eBay, they are swivel too. I bought hose from somewhere else, I forget who, it's 1/4" line.

I sadly cannot comment on how they are holding up because my car is still not running. The quality seems great.

I can't say how the MettleAir fittings will hold up to the corrosive environment of an engine bay. At work we use compressed air or nitrogen gas in them and they have held up fine. Also, yes the 90 fittings do swivel so you can reposition them. For ID of the hoses, I can't say.

Time will tell.

My Wastegate is cooled so I'm hoping those ones will last long, they are the only ones I'm really worried about.
