This FPR is trash. I’m on my third one and they’ve all started to leak within a few weeks. I’d rather not turn my car into a rolling ball of flames AEM. I’m very disappointed in this product. I expect better.

Tried many other brands and got leaks, improperly seated diaphragms and some leaking from vacuum side. This one was great. Installed and fired right up.

#1 fittings on the return line leaking apon initial install, needed to RTV it and over tighten it to get it to stop leaking #2 within 3 months of initial install the bowl on the diaphragm started leaking fuel, needed to RTV it to get it to stop leaking #3 within 3 months, 2 weeks of initial install the diaphragm popped inside, causing motor to stall & flood with gas, hydro-locking 2 cylinders and contaminating oil. Avoid this model if possible. big waste of my time. 0 stars
