Thanks for doing these videos. I’m steadily getting mine ready to drive. This is very helpful.

I’m a lucky one that had to cut the weld on my balance screw. Where did you get your screw?

[@Joesmusclecargarage]

@@niatt3537 It was the factory screw. I ground the weld off of it.

[@niatt3537]

@@Joesmusclecargarage Ok my screw head is much smaller than the one in the video. The head is pretty messed up now after the cutting. I’m just looking for a bigger sized head with maybe a nice knurling on it for easy adjustment. Thanks for responding. 👍🏻

@@niatt3537just take your old rounded off screw to a fastener shop, they should be able to get you what you need

How to get fuel to the injectors I can put a fuel pump electric and put a tube in a gas can and it will squirt perfect but when hooking back up to factory is not working what can I do

[@Joesmusclecargarage]

Is the in-tank pump turning on?

Can you tell me the type of balance water gauge you use I would like to try to find one

[@Joesmusclecargarage]

I explain it in the video. It’s a slack tube water manometer. You can either make one, or buy one.

[@seanhall4098]

can you use a vacum guage ? and if so do you know the reading for the 84 corvette ?

[@Joesmusclecargarage]

If you mean a standard vacuum gauge that measures in/hg, no. It must be measured in in/h2o. If you don’t want to buy a manometer, it’s easy to make one. There is no “reading”. The procedure for the LU5 and L83 is identical.Follow the steps shown in my videos and you’ll be fine.
