To be safe I've ordered all new Gate Barricade Fuel Injection hose between the tank, first filter, pump and last filter even though the pre pump stuff isn't high pressure.
Do you have any pics of your work there @edsnova? You really think 11 years of mild use is worthy of replacing all those lines?
I ran my hard lines alongside the tunnel. It's invisible under the carpet. Converted the original fuel line into the vent line to the charcoal filter.
Like Danny says, grommets:
Your Beck may have an access door (or doors) into the tunnel from underneath. If you put the car in the air you should be able to see, and if you have them you can inspect and change everything out more easily.
Honestly the hose is probably fine, but...while you're in there.
And yeah it's a PITA. My neighbor just finished putting his fuel and return lines in the tunnel of his Ghia. Pan is bare and he has 360-degree access but still took a few hours. He used hard lines, of course.
Finally, I must have been mistaken re your pump as compared to mine. Yours makes 98 PSI?? The pump in mine (I measured) generates about 38 PSI at the head with the engine off (it can go to like 45-50 when the regulator squeezes it). It's a stock 1995 EJ22 and it seems to like that just fine.
At 98 lbs pressure I'd be even more fastidious about fuel line maintenance.
It's useful to remember that the Subaru factory engineers got about 95 percent of what was to be gotten out of these engines, in NA trim—and it's more than plenty for a clown car. With the possible exception of head gaskets, it simply doesn't pay dividends to deviate from their formula.
