Quick facts
- Part: Standard Ignition PR127 fuel injection pressure regulator
- Fits: 1985-1987 Isuzu Impulse 4-cylinder 2.0L
- Condition: New
A hard start, a rough idle or a fuel smell can come from a worn regulator, but other fuel parts can also be behind them, so find the cause first. With the engine off and cool, look over the regulator and its fittings for fuel stains, wetness or cracks; a pressure test is a job for a shop.
Fits
