So I ordered Airtex e3240 pumps. Do they have the same connector as the stock pumps?

Yes. I installed these same pumps recently. Pretty straightforward. Replace those plastic hose clamps too! You'll need both 5/16 and 3/8 inch.

One more question. Are the o-rings for the fuel filter the same size as the ones for the rail?

ALLTHECAMS · 05-12-2019

Installed the new pumps last night. Tested amp draw after and it was 9.5x. Took the car for a test drive and it lost power on the highway while testing WOT. Got a tow back home (luckily I was only a mile away). Tested amp draw again and it was 4.3. Primary pump isn't running.

Blown fuse?

I checked the fuse and swapped it with another one. It's fine.

Bummer... when you pull the assembly again, check the connectors especially the one at the top of the of the entire assembly where the wiring exits through the top. Also apply 12v directly to the pump and confirm it is really dead. No need to replace the pump if it’s really something else. Most likely it’s just a bad new pump. It happens.

Thanks. Maybe a dumb question but which one is the primary? The lower one?
