How can I keep my boost gauge vacuum line from slipping off the intake mani nipple?

[Dylan0123]

How can I keep my boost gauge vacuum line from slipping off the intake mani nipple? It's tee'd into where the fuel pressure solenoid is attached to the intake mani.

The nipple doesn't have a bead on it, it's slick brass, and my vacuum line popped off of it twice. I put a zip-tie around the line, but I can still pull it off by hand fairly easily.

Does anyone ever rough the nipple up with sandpaper to give the line something to grip? Could I use some kind of thread sealant or other non-permanent adhesive on it? if so, what do you suggest? Or is that a bad idea in case chunks of it break off and get sucked into the line?

By the way it's an electronic boost gauge, if that matters. Do I need to have this inline filter (came with the gauge) on the line or is that even neccessary? Will that filter cause my gauge to be more inaccurate?

Thanks,
Dylan

If the line won't stay attached, some sandpaper and RTV might be a good solution. And you don't need the filter, it just stops dirt/water from getting into the sensor and potentially causing problems. Mechanical boost gauges typically don't have that filter.

Buy a piece of smaller hose and shove it on there instead, or if the end of your hose is ballooned a little just trim about an inch off and try again.

Adjustable Cable Tie Gun

try a zip tie gun similar to this. it will get the zip tie super tight more than you can get by hand plus a little RTV. if that doesn't work try some PL construction adhesive that stuff sticks anything to anything but good luck getting it off

Get a different T that is barbed.

Put a small flare on the end of it

I used a very small clamp on the nipple on the manifold for my hose. Very effective.

Don't use rtv, use hairspray. Spray a little in the hose and put it on let it sit overnight. Works on silicone couplers that won't stay on too. Leaned that trick from jafromobile on YouTube, he has a lot of great dsm vids.

Awesome suggestions. I think I'll go with sandpaper, hairspray, a tiny hose clamp, and a smaller hose. That should definitely do the trick. Thanks everyone!

Sandpaper
Clamp
RTV
Hairspray
Zip Tie

They all work like charms.
I should package all these up and sell a DSM Pipe-Stay Kit in various different sizes.
