I pulled out the Tube on the bottle ...all the way it would go....folded it over to not leak any and snuck it in from the top. Found the full hole with my fingers....inserted tube from bottle and squeezed it all in....easy as pie. Now that I think about it ....i thought it is easier if you remove the air box I thought afterwards also. I was just avoiding Jack's and jack stands
Yeah, I'm thinking pulling the airbox and not headlight would be best if you don't have a tube funnel and want to use the built in spout tube on the Ravenol bottle... And funny, I have ramps but not a jack and stands, so it's actually easier to do ramps for when just a little more clearance is needed. But also, I'm just resigned to the fact a tube funnel will probably be really helpful for me for other stuff so it would be worth the storage space, but always cool to share ideas here. I've saved myself lots of headache by using these forums to either read through threads for stuff I need to install or asking questions and even going back and forth on silly little shit like this helps to come up with the easiest way for me. For example, on the passenger side engine mount insert, it may have been you, but they said to just remove passenger side headlight, pop the coolant tank up and set over in the headlight area to get to it and that ended up easily being the best way, and that was well into the thread discussion... For this, I went with the pump from bottom method and really wish I didn't, but oh well, we win some and lose in our decisions working on our cars...
