1) parts you need:
Most everything is from harbor freight to save money:
20oz oil can: $4
compressor regulator: $5
1/4" brass coupling: $2
1/4" quick connect kit: $4
16oz of mineral oil from wally world: $2
used glow plug from my truck: free, but figure no more than $10 bucks if you have to buy new
used 12V battery: old car battery or battery backup (UPS) battery works
wires: need some alligator clips and 16ga wires to run battery to glow plug
compressor: i already have a 60gal standing compressor I used to connect to this. You can use a 10 dollar tire compressor from walmart.
total cost: $17 (if you have an old glow plug and battery) to $60
Did you found the leak ?
