Hydrometer is not needed for straight alc, just pour into tank and go.
Ran for years with a simple tool tray that set on top the injector and carried up to the start.
consisted of between round maintenence tools
Spark plug wrench
turn over ratchet
main jet wrench (along with a brick of jets)
valve cover speed handle
small cresent wrench for fittings
medium blade screwdriver
long needle nose pliers
dzus wrench
3/8 combo (injection jamb nuts)
7/16 deep socket and ratchet (ign timing)
.020 feeler gage (plugs and valves)
Rocker adj tool
ty-raps and extra dzus buttons
If you cant fix a problem with those, you dont have time to fix it and head back to the pits
Be sure to carry 2 chute packing strings on the back of the car, just in case it pops in staging.
No need to outfit the trailer like you are selling snap-on tools either. just the tools needed to put the car take apart and put together. Bought just the special socket needed to do the job at hand and not the whole rack, IE one 3/4-12pt for the converter bolts, one deep 1/2-12pt for the heads, 15/16 did the idler adjust bolt and the wheel nuts, using the turn-over ratchet, just the allen sockets needed for what is on the car, if nothing uses a size you have, leave it home
