- Quiet operation with no audible regulator noise
- Diaphragm materials made for longer life, durability and compatibility with a wide range of fuels
- Consistent, predictable fuel pressure throughout the system's range of control
Quick facts
- Part: Delphi FP10545 fuel injection pressure regulator
- Fits: 1970-1973 Porsche 914 H4 1.7L, the 1974-1976 914 H4 2.0L and other vehicles
- Condition: New
Hard starting, rough running or a fuel smell can mean the regulator is failing, though these signs can have other sources. Before you replace the regulator, rule out a weak fuel pump, a clogged fuel filter and a leaking injector, because any of them can leave fuel pressure low or uneven.
Fits
The 1970-1973 Porsche 914 H4 1.7L, the 1974-1976 914 H4 2.0L, the 1969-1972 Saab 99 4-cylinder 1.7L, the 1971-1972 99 4-cylinder 1.9L, the 1972-1974 99 4-cylinder 2.0L and the 1973-1974 Volkswagen 412 H4 1.7L all take this regulator, and so do other vehicles. Each engine takes a single regulator.

Frequently Asked Questions
Is Delphi FP10545 the right regulator for a 1973-1974 Volkswagen 412 H4 1.7L?
Yes, Delphi FP10545 fits the 1973-1974 Volkswagen 412 H4 1.7L. If your car is not one named on this page, look up its year, model and engine in the "Vehicles it fits" section.
Does the Delphi fuel injection pressure regulator handle high-ethanol fuel?
Yes. This regulator's Nitrile™ diaphragms are resilient against high-ethanol fuels, and the diaphragm materials are made to work with a wide range of fuels.
Is this regulator noisy in use?
No. Delphi FP10545 is built for quiet operation, with no audible regulator noise.
Can a failing fuel pressure regulator cause hard starting or a fuel smell?
It can, since the regulator holds fuel pressure steady. Testing pressure means opening the fuel system, so have a shop do it.
Does Delphi FP10545 replace number 7700545780?
Yes. That number is one of the cross-references listed for Delphi FP10545 on the Interchange line at the bottom of this page.
