Default fuel pump install quick question!

I'm in the middle of my walbro fuel pump install into my 03 wrx. I noticed that the new walbro fuel pump's hardline that stick out the top (the metal nipple thing) of it would "butt up" against the stock fuel hardline's metal nipple. there is basically no gap between the two where you connect em. will this hinder fueul delivery/performance or cause any problems?

The stock fuel pump's hardline is about 1.5 inches away from the other line.

I just cut the hose shorter and slid it up onto the hard line and put the pump right against the hard line ... Slid the hose down over the pump niple and clamped it like that. No problems in over 3/4 of a year it's been in.

You may get some very fine metal/plastic particles from the pipes rubbing together due to vibrations etc but that's what the filters for....

Is this the gss341 pump? Isn't the 342 a direct bolt-on that requires no modification?

That is a common question with the walbro. It will work fine.
