How to add fluid to the liquid Gaffrig?
 

Anyone do this? What type of fluid?
Thanks

it uses glycerin, call Gaffrig they have the fluid, should be a rubber plug in back of gauge to fill

OSO Member Too Old once said the that glycerin can be obtained at a normal drug store.

Thanks!

Just don't use Nitro-Glycerin.....one big wave....and......KABOOM. :crazy: :D

you can obtain the fluid from gaffrig for around 30 dollars including shipping. there was enough to fill the speedo at least twice. first make sure that the yellow seal is seated properly. to check, spin off the colored bezel and remove the face plate. the seal seats in between the flange on the face plate and the gauge itself. after replacing, the glycerin fill port, depending on the gauge, is either at the top, or just above the speedo cable plug in, remove and fill. the trick is to get all of the air bubbles out. may have to play with it in order to achieve. according to gaffrig, there should be a small pea size bubble remaining. good luck....ken 342 boss....speed dosen"t kill, boredom does!!!
