I called Spectre and was told that the pump in the FI fuel tanks is set @90psi. My engine builder says my LQ9 only requires 58 psi.

Why would Spectre make a tank with such an excess volume.

Can anyone help me figure this out?

Thats what a fuel pressure regulator is for. The fuel pump doesn't have a built in one, u add one on the fuel line. I don't know about 90psi maybe they are rated max flow. Most people are using the inline Vette fuel regulator.

I am planning on running the inline vette regulator myself. I just thought a drop from 90 to 58 psi seemed excessive. But it seems from other posts here that people like the tanks.

The pump in the SPI tanks is a Delco EP381, the same pump found in 96-99 5.7 and 7.4 GM trucks. The Vette pressure regulator will be fine for you application, as the trucks with the pump had similar regulators.

Where in Ontario did you get your tank from?

I would recommend rockauto.com for unbeatable prices on the SPI tanks. Apparently you can search google for an addition 5% discount as well.
