The FueLab 53501 Mini is a compact billet-aluminium EFI fuel pressure regulator with two -AN6 inlet ports and a -AN6 return, adjustable from 25-90 PSI (1.7-6.2 Bar) - built roughly 50% lighter than Fuelab's 515/525 Series.
Overview
The 535 Mini Series shrinks the standard EFI regulator down for tight engine bays and space-limited installations, while keeping the same 25-90 PSI adjustable range and mounting hardware as the full-size 515 Series.

How It Compares
Need larger -AN10 or -AN8 inlets at the same 25-90 PSI range? See the FueLab 51501 (-10AN, standard 515 Series) or the FueLab 59501 Ultralight (-8AN, 30% lighter).
FAQ
Will the 53501 fit in a tighter engine bay than the standard 515 Series?
Yes - it's the same EFI pressure range (25-90 PSI) in a body that's roughly 50% lighter and smaller than the 515/525 Series, built for exactly that.
Is this a carburettor regulator?
No - at 25-90 PSI it's built for EFI systems. For a carburettor, use the FueLab 51503 or 51505.
