Having problems with your 1992 Ford F150 SuperCab ?
I need to change fuel filter for 1992 f150 [relay diagram]
\015 I have no owners manual so I am in need of a layout of the power distribution box, or to I.D; the fuel pump relay in order to relieve the pressure. Thank You\015
To relieve the pressure, find on the fuel rail on the intake a schroeder valve, looks like a larger version of a tire valve, possibly with a cap. Remove cap, push center pin on valve to relieve pressure. Caution as high pressure fuel will come out, I hold a rag over it while I do it.
