Good quality, quick delivery

I ordered a fuel line kit and a fuel pressure gauge. The ordering process on their site was straightforward enough, no real issues there. It shipped out in about two days and I got it here in Colorado within five business days, which is pretty standard. The parts themselves seem well-made, the fuel line fittings were all clean and threaded on without a problem. I had a small question about the gauge installation, and their tech support actually responded to my email the same day with a clear answer. Overall, a good experience for what I needed for my project.

Another solid fuel surge tank

Got the multi-pump surge tank this time, and it's just as good as the single pump one I bought a few years back. Shipping was fast, same as last time. Always consistent quality from them, that's why I keep coming back for my race car builds.

Solid parts, but some wait time

I picked up a direct injection fuel rail and a fuel pressure sensor. The quality of the parts is definitely there; everything felt robust and fit perfectly. Shipping, though, took about a week to get to me on the East Coast. It wasn't terribly slow, but I've definitely had quicker from other automotive places. Customer service was fine when I emailed about tracking. So, good products and support, but maybe don't expect next-day delivery if you're in a rush.

Good value on an oil catch can

I was looking for an oil catch can and spotted one during their holiday sale. It was 10% off, which made it competitive with some other brands I was looking at. The shipping wasn't free for my order size, but the overall price still felt pretty fair. I don't usually splurge on parts, but the quality seemed better than some cheaper options, and that discount definitely pushed me to buy it. Glad I waited for the sale; it felt like a smart purchase for the money spent.

Anyone know if their catch cans are compatible with E85 fuel? Thinking of upgrading my fuel system.

M Mike 1 month ago

Most of their stuff is, yeah. I've been running E85 through my Radium surge tank for ages, no issues. Check the product page just in case though, for specific components.

D Derek Patel 1 month ago

Yeah, pretty sure all their fuel system components are E85 safe. It's a big thing for performance builds now.

Hey, wondering how long shipping usually takes for a fuel surge tank? I'm in Dallas, trying to get my build done soon.

M Mark 1 month ago

Mine took about a week to get to me in Florida. They usually ship pretty quick, but Dallas might be a bit faster.

D Dan Silva 1 month ago

Yeah, I ordered some AN fittings and they got to California in like 4-5 days. For bigger stuff it might be a day or two longer, but usually not bad.

Anyone know if there are any active coupon codes right now? Looking to buy a fuel pressure regulator.

C Colin 3 weeks ago

They almost never have public codes. Usually, discounts are only during big sales like Black Friday, or through their dealers.

D Dan L. 2 weeks ago

I've never seen a public code from them, honestly. Best bet is waiting for a holiday sale or seeing if a dealer you know has a special.

Are Radium Engineering parts actually good quality? I see some cheaper stuff out there, but want something reliable for my track car.

J James 1 month ago

Dude, Radium is legit. Top tier stuff, definitely not cheap knock-offs. They engineer everything super well.

R Renee 1 month ago

Yeah, they're not a fly-by-night company. Their products are made in the US and are known for being really high quality, especially for racing applications.

Is Radium a real company or just some random online store? Never heard of them until recently.

S Sam 3 weeks ago

They're a very real and reputable company in the performance automotive world. Been around for a while, making serious parts.

J June V. 3 weeks ago

Totally legit. They design and manufacture everything themselves, based out of the US. Not a drop shipper or anything.

Do they offer free shipping on smaller orders? Thinking of just getting some fittings.

N Nick Walsh 1 month ago

I think free shipping is usually only for orders over $500. For just fittings, you'll probably pay for shipping.

M Mike F. 1 month ago

Yeah, it's pretty rare to get free shipping unless you hit a high order threshold or it's a special promo. Fittings definitely won't get it.

How does Radium's fuel surge tank compare to Aeromotive's? Trying to decide which one to go with for my project.

N Nick V. 4 weeks ago

Both are solid brands. Radium's surge tanks are super well-designed for packaging and efficiency, often better for tighter spaces. Aeromotive is good too, but sometimes a bit more traditional.

M Mia N. 4 weeks ago

I went with Radium over Aeromotive because I liked the internal baffling design better for my specific setup. Plus, support for Radium has been excellent if I had questions.

What's the deal with returns if something doesn't fit? Just bought a fuel rail from them and worried about it.

J June Ito 1 month ago

I returned a fuel filter once, it was pretty straightforward. Just had to get an RMA and ship it back. Got my refund without any hassle.

D Derek 1 month ago

Their policy is usually pretty good, as long as it's not installed or damaged. Check their site for the exact window, I think it's like 30 days or something.
