This is about right, running the fuel lines is the longest part of the process. If you start with a GM harness count on 8-12 hours of adjusting the length to suit the installation. The upside is that you can still lump around on the carb until your ready.

For folks that are not 100% comfortable with EFI - leave the stock fuel/pickup in place..

I did the first time I converted to EFI, but I was also going from here to St Paul MN.. a 2 day drive on a new system so I wanted to be able to convert back to the Qjet in a hurry.

After a few months of have the Qjet bounce around it ended up on the shelf..

All THAT crap took some 40 hours of work. The Howell took probably 8. It worked first thing, EXCEPT it ran super-crazy rich. Howell was very helpful when I called!
