This fuel filter is mounted in the same area in a Corvette, above the rear diff. This filter will work fine at the rear of the car.
Corvette's also use a 3/8" fuel line to the front. With the RX7 5/16" line it should make a difference. A length of line will always have some head loss. I think it would be worth measuring. According to an online calculator http://www.lmengines.com/fuel_lines_calc
, the line size can make a big difference. For comparisons, I used the following numbers;
Flow = 1.1 gal/min (around 250 lph)
Hose I.D. = .215" (5/16"), .277" (3/8")
Line Length = 10' (FPR at tank), 3' (FPR at engine bay)
Elevation = 2'
It shows a big difference at a high flow rate, but not so much at lower flow rates. I was always told it was best to have your pressure regulator close to the engine. If it is adjustable, you can make up for it. Of course the Corvette arrangement is not adjustable.
Anyone else have some input on this?
