1998 GL1500 vacuum line replacement hose sizes?

Post by jikey »



Hi all,

I'm planning on replacing the vacuum lines on my '98 GL1500 SE and don't particularly want to go with the Honda brand replacements, if I can even find the parts these days. Can anyone who replaced the vacuum lines with non-Honda hoses tell me what sizes you used to replace the originals, and what lengths you bought? I know the pink cables around the air cleaner are 3.5mm inner diameter, but the stuff buried under the carbs I'm really not sure of, and would like to have it on hand when I actually need it.

Thanks,
J.

I got my sizes off the parts fiche for my 88. I just looked, and they are not listed anymore. Sorry, I do not remember the sizes. I did that project 9 years ago. I would check and see if the dealer can give you the sizes. They are metric. I just purchased bulk hose off Amazon. That was the only place I could find metric hose. The local auto parts stores do not carry it.

Here is a thread from another fourum. It shows the sizes and appx. amount to purchase. Lengths are in bulk. Vacuum hose is relatively cheap so any left over won't matter much. Good luck.

You'll need 3mm, 4mm and 6mm hoses:

Amazon: 3mm x 10 ft silicone vacuum hose

Amazon: 4mm x 10 ft silicone vacuum hose

Amazon: 6mm x 10 ft silicone vacuum hose

I had these pictures saved, not sure where they came from:
