I was unaware of the location of fuel filter, after dealing with low fuel pressure ( 20-23psi) and erratic stalling, ended up replacing the fuel pump module, which resulted in correction of low pressure and stalling. On dis assembling the fuel pump module came across the fuel filter which is integrated withing the module plastic housing. The fuel pump itself was fine and the filter completely clogged. The Van is 2002 and has 152000 miles on it. The filter is separate item from the fuel pump sock. The filter is not available separately hence need to replace the fuel pump module.
