Fri Nov 07, 2025 4:47 pm

I found that my '79 vert has been running lean and hot. The PO had replaced the fuel tank and all hoses when he revived the car after a long hibernation, but clearly there was still some smegma floating around. I could probably just clean the injectors, but I went ahead and bought the new injector kit from Injector Rehab. Unfortunately, their install video is for a vanagon, not a bug. I know it isn't rocket science, but I'd like to see video for an install on a bug. I'm sure there are some pitfalls and hick ups that someone else has already delt with when i comes to doing it on a bug. There's a lot less room on a bug on the sides than a vanagon. Does anyone know of a link to a video on this install on an actual bug?

Thanks,

Hans

Sounds like a question to ask the seller about, although aside from the cramped working space it's really no different from a type 4.

They haven't replied yet, but I would think that if they had it, they would have posted it somewhere. I searched you tube and came up with nothing.

It is a little different than a Vanagon. The bug has hard lines. There is one coming off the left side that goes across the front of the fan shroud behind the throttle body and somewhere T's off to a hard line that goes to the cold start injector and then makes it's way to the right side injectors. This kit has a fuel rail that is much wider than the stock injector set up. Are people abandoning the hard line and using FI hose or are they bending the hardline over to get a connection? It's those sort of things i'd like to know. This is a low mileage(18k) totally original '79 triple white vert. It's one thing to run none stock injectors that can be swapped back to OG in 20minutes. It's something else to bend the hardline and then one day have to try and bend it back and look right. It's not the end of the world, I just figure someone must have done this before and knows what angle they set the 90d fittings at and if they had to bend the hard lines to make things fit nicely

Although the modern injectors are a tanatalizing upgrade I'd be going to NAPA and buying some new replaccements for the OG system, a clean low miler is better off unmolested, and somehow milions of them got along great with the OG system.

Not all years of bug had hard lines, some used miles of hose in thier place, more fire risk perhaps and a little messier. If you want to want to go with the IR kit use hose, just don't cheap out on hose or clamps, FI rated Ethanol proof or don't even bother.

Knowing what a difference the modern injectors make in Vanagons, it was too hard to pass up the Bug kit. It plays well with the stock FI and it is easy to switch back for a sale or Pebble Beach. I may just do the full hose if it is too hard to hook up the hard lines. Having worked on my Vanagons for years, I know all about fuel hose...

I just can't believe that no one has done a video on it. I can find god knows how many videos of the most useless stuff on line, but not this. Maybe I'll have to make the video :-k

would you like to elaborate on the differences from the original Bosch set up...
