I've done some searches, but I was hoping someone here could help me out with some stuff Im still hazy about.

My fuel pump kicked the bucket last week. I have a carbureted car, but I have every intention of putting fuel injection back on it before the next fuel pump I purchase dies. That means I want a pump that is reliable. I am willing to pay more to make sure this happens.

I dont see my planned power levels realistically going beyond 400hp, maybe 450hp with a cammed LT1 or cammed LS 5.3 or something like that in a few years. For my purposes (autocross, hopefully track days) the extra money that it would take to beef up the driveline just isnt worth it and I'd rather invest all that money into suspension/tow rig/safety gear/tires. Power isn't really a concern.

So I need a fuel pump that can safely handle 400hp that can also handle being regulated down to 5-7psi through stock fuel lines for the next year or two.

So I've been looking basically at stock replacement L98 type pumps.

So far I've found out

1.the airtex pump is likely garbage.

2. The Walbro 255 is obviously popular, but I keep hearing about TONS of failures on those. I also heard they had a huge problem with counterfeit Walbros a couple of years ago that trickled into the main supply lines somehow. Seems like a convenient excuse to me. I couldnt find anything recent saying that Walbro pumps have become more reliable or less reliable since then.

3. The AC Delco EP241 was decent, but one of the fuel line fittings isnt the right size on it... which is allegedly not a big deal since you can just shove the line over it and clamp it. I dont know how I feel about that.

4. The Bosch 69218 might be good? ... not much else on that one besides one positive mention.

5. Aeromotive told me the Stealth 340 wouldn't work, just too much pressure to regulate down through tiny stock lines. They recommended the Stealth 200... which costs 3 times as much.

Do you guys still think Walbros are worth the money and time? Is there something more reliable that will fit my needs? Do I need to worry about an "install kit"?

I just installed a Walbro 255 but haven't started the car yet so I don't want to hear anything bad about them. I believe they are near perfect! How about an appropriate in-line fuel pump for now?

I've been running my Walbro 255 for a year (I know it's not very long) but it hasn't given me any issues. It is loud though.

Just fired it up and for the minute I ran it the pump worked fine. Time will tell. Interesting the remarks I've read about the noise. I couldn't hear it once the engine was running. But the muffler is still off. Sounds good.

several years out on the AZ pump, just don't use the quick connects for wiring, crimp, twist, solder, don't use quick connects............

Did you guys have to get one of those install kits? Or did it just bolt in as if it were stock?

I have the walbro 255 with the hotwire kit ( http://www.hawksthirdgenparts.com/pr...%27s-side.html ) on my list for my LS swap. I haven't heard anything bad about them. What are they saying? I would assume the conditions for the pump (too much pump for their setup) or maybe improper voltage may have have been factors for people who've had issues. But that's just a guess from what i know about pumps in general.

I have to say that Aeromotive Phantom Stealth universal pump looks like a nice piece. it would be difficult for me to make the cut to install it. I prefer direct bolt in replacement.

The question to me is... is this just due to the massive popularity of these? Or are they still having problems?

What cut is requires for the Stealth 340? I was under the impression it was more or less bolt-in. Maybe the stealth 340 is different from the "universal pump", though. I know they told me to get the Stealth 200 but it comes with some goofy install kit that's somehow worth an extra $300.

thanks for the links. I'll still probably go with walbro. Seems like a lot of good luck has been had with them also.

http://www.summitracing.com/parts/aei-18688/overview/ To install the Aeromotive pump you use a 3 1/4" hole saw. Lots of pluses to that design but cutting my gas tank for a single aftermaket design is a big minus for me.

Im not positive but I believe this is the one that's supposed to fit our cars.

And that Racetronix kit was available from Racetronix for $130 yesterday.... Today I see the FL98 kits are $30 off and there's no wiring harness included. I dont really understand what that's about. I wasnt really sold on needing that harness to begin with for my application.

I just installed
Walbro GCA758-2 - Walbro Electric In-Tank Fuel Pumps

That's the 255 lph and so far so good. Just ran it a few times now putting the rest of the back end in place. It was plug and play for me. This one comes with the "kit" as I've done one and didn't know for sure what I'd need. The one piece that I needed was the short "adapter" pigtail seen in the image at the other end of the link. It connects the pump to the existing electrical plug as the connectors are different. My install didn't call for the short pipe and clamps.

Thanks for the info. That helps a lot!

I meant to say I'd NEVER done one before. Also, just looked again at the image and it's not exactly what I got. The pigtail had the correct connectors at both ends so no cutting wires and the rubber cap that goes over the end of the pump was more egg shaped to exactly fit the bracket. So better than what the image shows. The new pump was just very slightly bigger in diameter than the existing pump but still fit in the bracket just fine.
