SPELAB's new design addresses being able to place a return sump under the factory sending unit in the tank. This is the sweet spot for all fuel levels. Having it forward or in the back of the sending unit can cause issues with low fuel during those rowdy moments stabbing on the throttle or getting on the brakes hard.
Only one hole to drill in the tank means fewer chances for a leak. Our sump ring also has more surface area than the competitors, so you have a more positive sealing surface.
Fitment Notes: Universal.
Feature: - It allows you to use every last drop of fuel in the tank, maximally eliminating air sucking when the fuel tank is not full or fuel tube is broken. - Suitable for high flow lift pumps, such as for Airdog, FASS and more; And fit for Duramax Powerstroke and other engines. - Constructed of high grade with special treatment, anti-oxidization, corrosion-resistant and durable to use. - Sediment collection features can effectively reduce the amount of sediment flowing to the fuel filter system. - Single-bolt is designed for simple installation. Only needs 4" diameter flat area on the fuel tank, metal or plastic, to be installed. - The inner ring is ready to go through the 3 inches hole so the tank does not need to be dropped. - Return Stand Tube eliminates your return fuel from being drawn back into the supply port. - 3" Hole Saw Included For Easy Installation.

Machining and overall finish quality is great, the integrated return with stand-off pipe is a really good feature along with the drain plug. Came with all the seals and hardware you need for the install. Looks great on my lml

Great Product
Everything fit like a glove aside from hose. The 5/8” hose provided is not very long. Had to obtain from auto parts store to complete neatly. Also missing gasket for oil side of turbo. Had to obtain from dealership. Great product aside from these issues.
Great product. Good price for an aluminum cover with all the extras. Fill, drain and fluid level view window are great options. Top notch product.

Not for a novice!!!
05 LLY Duramax. I soaked bolts for days in a penetration oil, used heat and had a bolt break off in turbo, which made install miserable. I also did mine while transmission was out. This would not be easy with transmission attached, just a FYI. Great product, decent shipping, but not sure what the bolts that came with it are for, because they were not even close to stock up pipe bolts. Had to retain stock mounting hardware!!

Like stock!
I was surprised when I removed the DPF/SCR and replaced it with a straight pipe with a high flow muffler… and it was quiet. But I don’t have to worry about getting pulled over. Easy install, very straightforward. Would buy again. Shipped fast! But if you want louder pipes, consider the straight pipe.
The exhaust sounds amazing. And very easy to install. Only complaint would be packaging. UPS destroys the box when delivered, if there were better Cushioning within the box, less likely to be damaged.
Worry-Free Purchase
