Customer Reviews
Got a great deal
I was looking for a new set of fuel injectors and saw they had a fuel system kit discount going on. It saved me a good chunk of change compared to buying everything separately. I definitely felt like I got my money's worth. Shipping was reasonable, and the parts were well-packaged. For someone on a budget like me, finding a deal like this made the purchase feel really good.
Fuel system kit is awesome!
I bought a complete fuel system kit and some braided fuel lines from Glenn's Auto Performance, and I'm super stoked! Everything arrived in perfect condition and the quality is just fantastic. Installation was pretty straightforward with the included instructions. My car is running so much better now. I will absolutely be shopping here again for my next project. Highly recommend them to anyone needing performance fuel parts!
Good quality, fast shipping
I ordered a sumped fuel tank for my Mustang last week. It got here pretty quick, took about 4 days to reach my place in Texas. The tank looks solid, no issues with the welds or anything. Haven't installed it yet but everything seems to be in order. The whole process was smooth.
Consistent quality, returning customer
This was my third order from Glenn's Auto Performance; this time I picked up some AN fittings and a billet fuel filter. Just like my previous purchases of the sumped tank and fuel rails, the quality was top-notch. Their parts are always consistent, and I never have to worry about fitment or durability. It's why I keep coming back for my builds. They always deliver solid products and I appreciate that reliability.

Can I stack a military discount with a free shipping code at Glenn's? Or is it usually one coupon per order?
Thinking of buying a full fuel kit for my Mustang, but worried about getting stuck with it if it doesn't fit. What's their return policy like?
Anyone know if Glenn's Auto Performance is legit? Seeing some good prices but wanna make sure it's not some sketchy site.
Hey guys, thinking about getting one of their sumped tanks for my Foxbody. How long does shipping usually take to like, California?
Does Glenn's usually have any sales around tax season? Looking to upgrade my fuel system soon.
