The Fuelab fuel gauge with SKU 71511 is out of stock. Do you offer equivalents?

Yes. We always suggest an equivalent part at the same cost when possible, for example the Fuelab 71511 fuel pressure gauge (0–120 psi with dual bar/psi scale) instead of 71501, the Fuelab 52501-1 E85-compatible inline 6AN regulator, or Nuke Performance fittings of the same quality. You decide whether to accept the change or wait.
