My husband and I own a diesel repair shop,so naturally I drive a diesel, a 6. 0 powerstroke to be specific. Anyone who drives a 6. 0 knows the certain struggles owning one. I went through 11. . . yes 11 sets of standpipes in 3 months time until i found out about dieselsite standpipes. And I have had them in my pickup for about 5 months now without any issues! These are the most durable built standpipes on the market. You will not be disappointed. Thank you guys at dieselsite. . these are a game changer.

Excellent customer service and support. Best set of standpipes I’ve ever used. No more roadside standpipe repairs with diesel sites new and improved standpipes. Worth every dollar.

I purchased the adrenaline hpop April 2023 and now March 2025 it’s leaking and I don’t drive the truck very much maybe 5k miles a year. Diesel site doesn’t stand behind their pump. My diesel mechanic found the pump is leaking from the non serviceable plug. Diesel site is sending him an oring and I have to pay to have their pump fixed. So much for the 3year warranty that’s worthless. Don’t buy from them.

Ordered mine. They came in and are nice quality. However the fitting for the hub did not fit. The fitting from the new lines are too big

Hands down best customer service/support I have ever expieriened. You guys rock 10 stars. Thank you for next day mailing me my reprogrammed ECM Cameron!

Installed so far so good truck runs absolutely stunning going on 100km so far way more throttle response is insane great that it comes with warranty aswell must be a good part

I just received my 2 micron filters for my 2015 ford diesel these filters work great they have been on my truck since it was new with no problems they are so easy to change and even easier to check. Great product!

Recieved the right ammount of studs but only got 4 need 5 I saved one of the factory studs so I will make it work.

Got the right ammount of studs but only 4 long and I need 5 I saved one of the old studs so I will make it work

absolutely disgusting customer service and i will never shop here again. there are plenty of decent diesel sites with excellent customer service. I suggest that you find a better site, one that isn't apparently owned by millennials; one where the company values its customer base....I complained about their terrible service and in response i received an email in bold font, telling me that if i didn't like their services, i could basically go kick rocks and shop else where.

I recently installed a Adrenaline HPOP in my 2000 7.3 powerstroke. Unbelievable difference in starting up, the engine runs quieter and smooth with much better response at the pedal. Thanks to Jennifer and Family for keeping us old Powerstroke alive. Excellent service

Amazing customer service! I won’t buy from anywhere else other than diesel site strictly for that reason! Thank you

Less than a year and less than 12000 miles the left hand side bellows cracked wide open!

My Adrenaline HPOP failed but was still under warranty. I needed my truck for July 4th camping trip. They paid to overnight me a new pump so I didn’t miss the trip. Outstanding customer service! Looking to buy more products from them after this experience. 10/10 recommend.

The holes for mounting bracket for the filter were off. So I had to elongate the hole closest to the fan. Other than that everything fit up nicely and looks great. I do wish the #8 hose clamps for the tee were bigger. Had a hard time sliding them over the hose with the tee on without having them all the way loose

Their billet hpop and hoses are amazing. I messed up while installing them and gave them a call. Super helpful and made my problem their problem. They quickly went out of their way to help fix my mistake. Really appreciate the help and fantastic products.

Seems to be a good quality pump with nice fitting gasket. Once installed and started the truck the belt would ride up the WP pulley on the block side. Didn't want to do the job again but instead pulley the power steering pulley out a bit and that fixed the issue. Thought ide share this incase someone else runs into same issue. The company stands behind there products and were willing to exchange for a replacement.

I tow a 15K# fifth wheel and came to expect the boot blowing off with regularity while towing. I tried all sorts of failed remedies Intel I found the Diesel Site. Boot. Seven years later it has performed flawlessly. I don't worry anymore about where I'll be when the boot blows off.

Had a new HPOP go down. They 2nd day shipped me a new one so I could be ready for the weekend. Super nice, Super Pro.

this company really provides maybe the best customer service i have experienced in quite some time. stand behind their products with lightning quick turn around on warranty work. i’m a customer for life!!
