Default OEM Fuel Pump basket

So I had modified my fuel pump assembly when I installed my Vortech & Walbro...drilled the fuel pressure regulator out, discarded the yellow nozzle, and drilled holes into the housing. Ever since then I had problems starting the car only after filling up on gas. I thought it was the injectors or some combination of things, but I removed the Vortech and am back to stock injectors now. The problem still persists, so that leads me to believe the fuel pump assembly is to blame for the starting issue.

Does anyone have a solution to this or have a spare fuel pump assembly available? I still have my OEM fuel pump, so I'll just need the assembly.

I think you damaged the assembly. Just have it replaced.

The car runs normal 99% of the time. The car will start, drive, restart just fine. The only time it ever has issues is after I fill up on gas. It will crank for about 5-6 seconds after which I'll pause. Then I'll crank again and it will slowly gurgle to life.

So you're saying a damaged assembly will cause this specific problem? I'm not going to spend upwards of $300 something to replace the assembly for something that happens once a week and causes me to just crank it a few extra seconds.

Sounds like you hurt the regulator and it is not holding pressure. What do you mean you drilled out the regulator?

H: Remove the factory fuel pressure regulator by removing the plastic retainer clip pointed out in FIGURE
19, and prying the regulator out with a small flathead screwdriver.

I. Carefully hold the regulator in a bench vice (or similar) and drill out the bottom orifice using a 7/64” drill
bit, only until the drill breaks through the first thickness of sheetmetal (about 1/16” deep) SEE FIGURE 20. This step is necessary because the orifice size restricts the flow capacity of the upgraded fuel pump.

I think I have a full assembly out of an '05 G35 (basket, pump, etc). If I still have it I would be willing to sell it, but only as a unit.

Let me know how much. I've got a few inquiries through salvage yards pending too.
