2013年7月30日 · Rotary pumps produce constant pressure and is what you want (need) for an EFI set-up. Inline/pulse/solenoid pumps produce pressure in pulses, like your mechanical fuel pump and are fine for carbureted applications. Neither pump will help with drain-back unless equipped with a check valve. Some have internal checks, most do not.

2024年7月26日 · So fuel goes from tank via mechanical pump to the sump, then the electric fuel pump feeds the fuel injection which returns to the sump through a regulator. The sump then returns to the stock tank via stock fuel line. Super easy to toss a carb back on this way if you have to for some reason. But it's also a very proper way to do a fuel system.

2025年2月17日 · As for fuel injection we've had good success with the sniper but for tuning beyond the hand held tuner you will need to buy the appropriate cable and tune it with a laptop. By the time you buy the unit, splurge for a good tank with in tank pump, run the new lines etc. id go with a new or known Straight bore carb and you're up and running.

2024年12月19日 · Throttle response is instant, and it fires as soon as you hit the key, even on hot starts. Still need to drive it and I'm sure there will probably be a few hiccups to work through but so far I like it. I may swap to an in tank pump eventually. the ptfe fuel line is so nice to work with, goes together easy. i still need to tidy up the harness.

2024年10月7日 · Aces' Killshot EFI system is one of the most advanced throttle body injection (TBI) systems on the market. The Killshot utilizes four 100 lb/hr fuel injectors, giving the system the capability of supporting up to 650 horsepower. The system includes the throttle body (with integrated fuel...

2017年1月18日 · I Finally thought to break out the ether and it started right up. I was frustrated to say the least. I waited till the next day and called Fitech and we finally traced the problem back to the fuel command center. they told me to take it apart and 1st thing i noticed was the pump inside of the fcc was cracked and not letting the pump build pressure.

2025年1月24日 · To properly supply the carburetor and the System, use a fuel pump designed to operate between 4.5 and 7 psi with a flow rate of 0.1 gallons per horsepower at 6 psi. For example, an engine that produces 350 horsepower when the System is activated will require a fuel pump that flows at least 35 gallons per hour at 6 psi.

2012年2月19日 · I also have the Powerjection. I can say that the install was VERY easy and straight forward. I am using the included pump now, but only time will tell if it lasts. I am really impressed with the ease of the system and how well it works. And the best part for me is the that the powerjection system can use a s/c or t/c up to 21 psi!!

2011年5月31日 · I used to run one on my F100, put it on in 1990, that pump is on the shelf now, still works great but as a 43 yr old I cant stand the noise LOL 70 Sportsroof, 427 FE, 489 cid, 10.7:1, Erson valvetrain, KC ported Edelbrock heads, modified Massflo EFI, …

2011年8月17日 · 1) Make a mount for the electric pump near the gas tank, and install said electric pump (Mallory 4060FI) 2) Run a return line one size larger than the stock line. I haven't decided how I'm going to do this yet - the line needs to come out on the passenger side of the firewall, so it can go right up to the regulator near the back of the intake.
