I am looking into using a differential cooler for my ITB Volvo 240. Diff. coolers are not in the ITCS, unless I completely missed a line in the drivetrain section. The Volvo Factory 240 Turbo's of the '80's used a Facet fuel pump and I'm not sure which flow rate to get.

Facet (square) solid state: 4-6 psi max, 15 gpm @ 3 psi, 32 gph, * AN-6 fitting size
Facet "Sliver" top (cylnder): 4-5 psi max, 23 gpm @ 2 psi, 36 gph
Facet "Blue" top (cylinder): 6.5-7.5 psi max, 35 gpm @ 2 psi, 45 gph

I am basically drawing suction from the drain plug (thru the cooler) and discharging through the filler in the diff cover. I plan on using -8 or -6 hose with an inline filter.

I'm not worried about weigh as my car has to weigh 2780# and it is going to be way under that without ballast. Not to mention this weight is low in the car.

Any recommendations?
