Throttle body hoses

[Bradders]

Hey everyone, I've done a search on the forum and haven't seen this question asked before, but apologies if it has.

I was balancing my throttle bodies last week and one hose broke off an about 10mm when I removed the hose leaving it a little shorter than the rest. I'm assuming this won't cause an issue as it's measuring pressure not volume. But, I do like things to be neat and tidy, does anyone know what type of hose and joints are suitable for replacements? I've found the Suzuki genuine element which adds up a bit when I put it all in the basket for nothing more than some hose and connectors. I was thinking of using some aftermarket bits, does anyone have any suggestions? Or am I better biting the bullet and going OEM?

Thanks

Your T pieces should be okay to reuse and as it's just air any 1/8" rubber hose will do the job but I don't know where you would get it from, try fleabay.

They are actually measuring vacuum (because manifold pressure is lower than atmospheric) if you want to be pedantic & the slightest split in them will cause poor running at low speeds & low throttle. it's a known thing they go brittle with age & it sounds like you're are overdue replacement.

Any car spares place does vacuum hose, you want 3.2mm ID which happens to be the only size halfrauds sell. You'll need about 80cm to change the lot. I have broken a Tee piece doing one set, but again generic stuff from a shop/ebay is fine as they are standard sizes.  If it's still fitted, don't forget the one to the PAIRs valve (the 2nd pipe off no3 TB), it's the same pipe in the same conditions.

Yup, std vac hose and some barbed plastic fittings off ebay will sort it out.

Thanks everyone, I'll take a look at that. I've got to say I've been suffering with intermittent slight hesitations when accelerating from low speed, I've put some liquid moly cleaner through and gone for good ride tonight and it seems to be running sweet as a bit now. I think I'll definitely change the hoses though as Hooli said they may be original so an issue waiting to happen.
