I Think Edge possibly.. use the Walbro GSL 393 , can depend on type of motor
normally aspirated or turbo and total boost psi...
Walbro GSL series inline fuel pumps are ideal fuel pump replacements and upgrades for: - Vehicles with faulty inline (external) fuel pumps. - Vehicles with expensive or hard to replace intank fuel pumps. - Vehicles used for racing or performance purposes where higher pressure fuel is necessary.walbrofuelpumps.com

Our newest Dual light weight pumps for our EFI kits. Suits all EFI kits or applications. Also suitable for 912iS. Pressure tested to 65PSI. Normal operating pressure is 35-45PSI set on the fuel pressure regulator. We use a 3-pos switch (ON-OFF-ON) and run one pump as main, and the second as a...shop.edgeperformance.no
Hmm. I thought they used Bosch but may be Walbro is what they use. They are also good fuel pumps. Fuel pressure measurement on iS is to be done in differential manner against manifold pressure and that has to be 38 to 45 psi. Absolute fuel pressure measurement is useless. I made that mistake in the first installation.
Anyway, fuel pressure measurement is an optional measurement for Rotax. Because as soon as you have any drop in fuel pressure you will know in about one second as engine will start to shutdown. Looking at fuel pressure does not give you any more time. It’s just a good troubleshooting thing. Useless for safety as you will have the same result with or without it in a second or two.
