FPR Replacement Housing - Billet Aluminum finished in a satin black anodized process
 
With 3 springs to allow you to set your fuel pressure to the performance levels that you wish to achieve  
 
If you have broken the threads from the fragile stock housing or if you just want to increase your fuel pressure for better performance, this Heavy Duty billet housing with interchangeable springs is your solution. Manufactured to OEM measurements, it will easily replace the cast factory regulator housing.
 
The recommended installation procedure is to install the cap with the fuel bowl removed from the engine bay. You will need to purchase the compression sleeves for all 4 hard lines attached to the fuel bowl separately as they are not reusable seals. (part # 7-004; 7-005; 7-006)
 

Three different fuel pressure spring settings*
 
  1. 58-61 psi  silver spring  (Stock pressure)
  2. 62-65 psi  gold spring
  3. 67-70 psi  black spring
 
 Also included in the kit is a new housing to fuel bowl o-ring and 2 new black oxide mounting bolts.
 
Due to the extreme weakness of the factory housing where the threaded compression fitting meets the housing body, we have received numerous calls from customers that have broken the threads off of the factory housing. Usually when this happens it is necessary to cut off the flare end of the hard line in order to remove the broken piece and compression nut from the line. The hardline then needs to be re-flared but it is now shorter and may be difficult to connect back to a factory housing.
 
With this in mind, we have made this housing wider than the original to compensate for those that have had to cut the end of the hardline off to repair this defect.

WARNING:

We are beginning to see some FPR rebuild kits offered on eBay and Amazon that supply a new FPR poppet valve. These poppet valves are from a 6.0L Ford engine and not the 7.3L engines where the fuel systems work quite differently. The Ford 7.3L engine FPR poppet has a small pressure relief hole in the end of the poppet to allow the fuel pressure to drain down when the engine is shut off. Without this relief hole, the fuel system remains pressured up, causing potential damage to your injectors and can cause fuel system leaks when parked. We also see kits for sale in these same venues that sell FPR springs that will overpressure your system and cause leakage and injector damage.

 
With these items beginning to appear on the internet, it is obvious that we have some very unscrupulous sellers that are offering products that will damage your fuel system and they know nothing about the mechanical operation of the vehicle that they are selling these items for.

Fuel Line Compression Sleeve
Please note that the fuel compression sleeve that seals the return hard line to the FPR housing is NOT reusable. The old sleeve will come out in at least 2 pieces, if not so dried up and cracked that you will have to remove the pieces with a pick tool. If you attempt to re-use a compression sleeve after it has been in service a few thousand miles, it will leak. Order a new Parker compression fuel sleeve from the drop down menu at the top of this page.
*Note: Fuel pressure data was gathered by using a analog mechanical guage on a test bench using a 2001 fuel bowl with no fuel filter and a Walbro GSL-392 fuel pump. The housing was then moved to live testing on a 2002 7.3L F350 and using multiple springs, a digital fuel pressure gauge rated at 1/2 of 1% accuracy and a stock Ford Bosch fuel pump, identical data was collected. Due to accuracy tolerances of various pressure gauges and spring tensions from the manufacturing process, your pressure readings could have variances from these results.
