HFP's Dual intank setup for 99-02 F-Bodies. Our dual pump setups use OEM float tested assembies with [2] HFP-255LPH pumps installed, secured inside the bucket using a welded fixture. This is NOT a floating pump setup where the pumps just sit inside and pull on the hoses. We use an s-hose out of a 400-812 Walbro installation kit for a 5.0 Mustang, and an Eldon James stainless steel Y-fitting. The first pump uses a repinned factory wiring connector - no splices here. For the 2nd pump, the harness leads out of the top of the assembly and is ready for a Hobbs switch. There is a $100 core charge for these dual pump setups. Send back your original assembly in good condition, and we will credit your account.
