Ask any experienced food truck operator what they wish they had known in year one and the answer comes up constantly: keep spare parts on the truck. Not a full workshop inventory — just the 23 items that fail the most often and are cheap enough to stock without breaking the budget.
This checklist is built from conversations with active food truck operators across the US and cross-referenced against the most-requested parts in the FlavorFleets Market parts database. Everything on this list costs under $150 and most items run $10–$50.
1. Igniter electrodes (2–3 spares per burner type)
Every gas burner has an igniter that fails. A single electrode costs $8–$15 from suppliers like Tri-Star Restaurant Equipment.
2. Pilot assembly orifice tips (2 pack)
Tiny, easy to lose, impossible to cook without. $12–$20 for a pack of two. Match to your burner brand.
3. Thermocouple (1 per gas appliance)
A bad thermocouple shuts off gas flow as a safety measure. Stock one per fryer, one per range. Cost: $15–$35 each.
4. Fryer basket (1 backup)
Fryer baskets warp and handles break. A replacement Vollrath or Winco fryer basket runs $18–$40.
5. Flat-top griddle surface scraper blades (10 pack)
$6–$10 for a 10-pack. Used daily.
6. Door gasket (1 per refrigeration unit)
The single most common refrigeration maintenance item. True Manufacturing and Beverage-Air gaskets run $25–$60 each.
7. Condenser coil brush
A $12 coil cleaning brush used monthly prevents the most common cause of compressor failure.
8. Replacement thermometer (digital, NSF-rated)
Stock a backup NSF-certified digital thermometer ($15–$25) in case yours fails before an inspection.
9. Spark plug (2 spares per generator)
Honda EU2200i and Generac GP3300i spark plugs cost $4–$8 each. Change them every 100 hours.
10. Air filter (1 spare)
Generator air filters get clogged with grease and cooking exhaust. $8–$20 depending on model.
11. Oil (1 quart, generator-rated)
Generators need an oil change every 50 hours. Keep a quart of 10W-30 on hand. $6–$10 per quart.
12. Fuses (assorted pack)
A $10 assorted automotive/generator fuse pack covers most electrical failures.
13. Water pump (1 backup)
The 12V water pumps used in most food trucks (SHURflo 4008, Flojet 03526-144A) cost $45–$120. A failed pump means no hand sink and no service.
14. Hose clamps (assorted, 6–10 pack)
$8–$15 for a variety pack. Hose clamps loosen from vibration and cause slow leaks.
15. PTFE thread tape (3 rolls)
$2 per roll. Keep rolls handy for quick connection fixes.
16. Fresh water tank cap (1 spare)
Often cracked or left at a fill station. A replacement cap runs $5–$15.
17. Shore power cable (30-amp, 25-foot)
Your event shore power cable gets driven over and borrowed by neighboring trucks. A replacement L14-30 cable runs $35–$80.
18. GFCI outlet (2 spares)
GFCI outlets in food trucks trip and fail regularly. A replacement is $12–$18 and takes 15 minutes to swap.
19. Circuit breakers (assorted for your panel)
A 20-amp and 30-amp spare cover most scenarios. $6–$12 each.
20. Fire extinguisher (1 backup, Class K or ABC)
A Kidde Kitchen Fire Extinguisher (Class K) runs $35–$65.
21. Grease filter replacements (1 set)
A set of mesh baffle filters for a standard 48-inch hood runs $35–$80.
22. Nitrile gloves (3 boxes)
$12–$18 per box. Run out during a shift and service stops.
23. NSF cutting board (1 backup)
A backup NSF-certified polyethylene board ($15–$35 for 18x24) keeps you compliant if your primary board fails inspection.
Stocking all 23 items costs approximately $370–$680 depending on your equipment brands. That is less than the cost of one missed event or one emergency expedited parts shipment.
