The module requires a 4th-gen LS1 fuel pressure regulator ($50 or wherever you can find it cheapest). The tank should come with the necessary part to adapt the regulator to the module.
The regulator that comes with the module will not work with our setups.
The output is single line, 58psi, the same as LS1, LS2, etc up until the latest LS/GM versions that use a fuel pump control module.
Sorry, but I'm not familiar with Accell systems or their pressure requirements. If it is possible to tune it to 58psi vs. another standard (42psi) then that may be a good option.
nother question. Is the fuel sending unit in this module compatible with a 90 ohm autometer fuel gauge? I think there are two versions of gauge senders and need to know about this factory type.
The 0-90 ohm will be a standard float-arm sending unit that mounts via a flange on the manifold plate of the tank. A similar 33-240 ohm sending unit is also available. The OE type that attaches to the module is 33-240 ohm and requires a longer flat section on the lower/forward section of the tank.
