Second time buying from Hotrod fuel hose

I purchased a return style kit earlier this year for my 90s silverado i was putting an ls in. I was very pleased with the shipping and communication from the company before i even received my package. Shipping was fast and when i got my package i was pretty happy with the quality of fittings and fuel hose. I had a few questions and customer service replied within minutes of me sending the email. Great company and great products i recommend them to anybody looking for quality. This product is where its at.
