Re: Convert a Fuel Injected XJ to Carburetion
If you can muck about with a carb, you can learn fuel injection. It is not really that hard. Though true that EFI has single points of failure, it pays for itself in the long run... though you already know that... and are kickin' against the *****s... so to speak. You not only need to think about the engine modifications, but the fuel tank as well. That fuel pump throws out about 43psi of fuel to the fuel rail. The modification would require you to most likely fab a new fuel tank. I'd be surprised if a sender from an older tank would fit. Then what would you do for a fuel pump? The engine doesn't have a place for a retrofit. That means you're stuck with an early generation 12psi (or there abouts) electric fuel pump and a mechanical regulator to what ever carb you choose.
IMHO, you're far ahead of the game learning the EFI and squirreling a way a few sensors and a fuel pump in your spares kit. My EFI swap on my I6 has been much more reliable. It has let me down twice. The total cost for the repair was $12 and 45 minutes time to repair. When I say it let me down the fuel delivery did not fail. The engine still ran, but it ran rich. My fuel efficiency went from 13.5 mpg to 19.5 mpg. The modification paid for itself in 6 mos. of gas savings at 1996 fuel prices. I can't say that about a carb, any carb.
Do yourself a favor, and forget the carb swap. You're doing yourself a GREAT disservice. Get a good manual on the Jeep, learn the EFI system and ask questions, lots of questions. There's no doubt that there is a learning curve when you study EFI, but it's not insurmountable.
And the good part.. there's lots of guys that are dumber than you who've done it... so can you.
But, on the other hand, it's your Jeep, your dream, and your money. [img]/ubbthreads/images/graemlins/grin.gif[/img]
