What has slowed the process, is the route of the pressure line to the gauge; I don't want to drill through the firewall, and with freezing weather, I will delay crawling under it! I am convinced I am getting reverse fuel flowing after shut-down, which empties the mechanical fuel pump or close to it? I would also like to install a one-way check valve up-stream of the mechanical pump. Does that FPR screen apply to my 89' vintage?? From what I have read, it is for the later models 96'+?? Or maybe I'm confused?------------LEE
Mine's a 94.5 year model and it had the FPR screen, on mine the screen didn't show any sign of debris when I checked it a few years ago. I don't have any idea whether the older vintage engines had a similar screen, but they might.
As far as going through the firewall, on mine I found a diamond-shaped plastic plug that pried out to reveal a hole right above the accelerator pedal (maybe a couple of inches above the pedal). For folks with an automatic tranny, there's also supposed to be a plastic plug in the firewall where the clutch master cylinder would mount to the firewall (off to the side of the brake master cylinder).
