JIC FPR Billet Housing w/ Pressure Shim Springs 99-03 7.3L
Our JIC FPR housing allows you to upgrade your stock return and supply your own -6 JIC return hose.
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 3 hard lines attached to the fuel bowl separately as they are not reusable seals. (part # 7-004; 7-006)
Three different fuel pressure spring settings*
- 58-61 psi silver spring (Stock pressure)
- 62-65 psi gold spring
- 67-70 psi black spring
Also included in the kit is a new JIC FPR housing to fuel bowl o-ring and 2 new stainless steel mounting bolts.
| *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. | |
