Fuelab 535 EFI Adjustable Mini FPR 90-125 PSI (2) -6AN In (1) -6AN Return - Black
SKU: F00B 53502-1-G
Moderate — 2–4 hours
Overview
This compact regulator weighs 50% less than Fuelab's 515/525 series, making it ideal for installations in limited space. It includes a versatile mounting bracket and stainless steel hardware for easy setup, as well as 1/8” NPT ports for an external pressure gauge and a pressure reference fitting. The fine thread pitch allows for precise pressure adjustment.
