The SPE Dual Pump Insert is designed around customers needing only two pumps without the excessive cost of a full billet 3 or 4 pump hat setup or an expensive factory style twin pump FPM. The insert design allows the customer to put together a return style fuel system inside the pump assembly that's already in the car. It retains factory operation including use of the bucket and siphon circuit which makes it much easier to put pumps in vehicles that have many different factory pump configurations like the F150 (due to different tanks for bed and cab lengths, etc.).
The SPE motorsport dual pump insert kit fits all 39mm style pumps including 255LPH all the way up to 525LPH hellcat pumps. They are retained and isolated by o-rings in a billet pump holder. The pumps feed a one piece billet manifold with a built in siphon port. From the manifold It feeds a custom -8 bulkhead which serves as the new feed. The factory fuel line is able to be reused as a return hose. All the needed components are included to install the pumps into a factory FPM.
