I'm looking for a fuel pump for a car that I've been working on.
Considering an EP381. A stock V6 pump might be adequate, but a little extra is okay, too. (This for a "very mild" turbo install on an otherwise stock 2.8.)
The question is... since everything is made of "chinesium", these days, where are people sourcing genuine/reliable pumps?
They're all over e-bay and Amazon, but I don't want to have to do this over, for having installed a "knockoff" pump.
TIA!

I bought Rodney's v6 fuel pump, it installed well, is cheap, and is ample for a 3.4l running at 14psi boost, I don't know whether it is rated for that amount of fuel flow, but it is working just fine. From what I've read I think the Fiero v6 pump is just a plastic version of a pump that is on some v8 engine, maybe a Corvette or something, I don't remember, only difference is some internal parts are plastic instead of metal.

I saw that, but wasn't sure about the capacity. Probably a better bet than anything else that's floating around out there. Rodney always was "top shelf".
Thanks!

As you probably know, the stock 2.8 Fiero pump is also stock on the old 4.9 Cadillacs.
I can't imagine the stock pump wouldn't handle your build.
Standard has been a good brand, do they list one?

I actually use Rock Auto for a LOT of things. The biggest benefit I've realized is that you can pick and choose what you want to buy... they offer dozens of different makes and models of every part, and then I can do a little bit of research on them. Sometimes they'll even tell you where the part is made.
But... more importantly, the "closeouts" are the best part of Rock Auto. Incidentally, close-out deals are the lowest price, almost always... best bang for the buck. But why I really like them is, these are parts that are often "found" by a supplier somewhere, and then provided up through Rock Auto (almost like on Amazon, if you will). These are almost always parts that were manufactured years ago, and that specific company no longer produces them. Take for example, TRW. TRW, hands down, made some of the best suspension components. They don't make these components anymore for the Fiero... but every 6 months or so, a few sets of TRW ball joints pop up on Rock Auto, and they'll sell them at 1/3rd the price, and list them as "close-out." These are all made in America parts, and have thicker casings than the other parts. People often don't buy them because they see close-out and they think crap... but it's almost always the exact opposite.
In buying parts for my daughter's car, almost everything we bought (if possible) was on closeout. The cheaper price helped, but it was really because I wanted the higher quality "new old stock" stuff that you just can't get anymore.
Only thing I'd add about fuel pumps... if you go with a pump that's significantly more flow than a standard replacement pump, I've heard that it can add unnecessary stress on the stock wiring, and could result in blown fuses and such. I don't know if that's true, but the people on the Corvette forums complain about that constantly. Everyone switches to a higher pump since it takes 10 minutes to swap one out, and people end up with burnt wires.

Thanks to everyone for your responses.
I ordered Rodney's pump. Figured I wouldn't go wrong, that way.
I also didn't realize that the Fiero and 4.9 pumps were the same, but it's not really surprising.
I probably should have ordered two pumps, since I'm going to start on my "LQ1 into a base coupe" swap, as soon as I get this one out of here.

Have received good function and performance with Bosch fuel pumps that are made in their own factory in Brazil. Have one in my 3800SC that has already lasted 15 years. Delphi products have also proven to be good. While Made in China their quality control standards appear to better than on many products made there.
Don't use Airtex /Mexico brand. They are junk

The stock V6 fuel pump part number cross-references to about a couple dozen other GM models from the 80s and 90s. Finding one locally or online shouldn't be difficult.
I'm currently running a Delphi pump I bought at O'Reilly's.

The 255 WALBRO is what's used on highly modified 3800SC builds.
It has the same shape as the Fiero, but is massive overkill for a 2.8.
