Ask Bill about carbing a DeLorean and other K-Jet/Carb tangets

[sean]

I don't understand how a coke bottle could possibly provide enough pressure to push fuel through a fuel injector unless you run a hose inside the car and have a passenger squeeze the bottle while you drive.

Where did Ron say anything about injector? He just needs a place where air gets in.

Doesn't an EFI system have to push fuel through injectors? Surely you can't run an EFI conversion on air alone.

All you need is air mixed with the fuel, doesn't necessarily have to come from the injector ports.

Who says it has to go through an injector? Haven't you ever made a home made "nitro boost" out of a can of ether and a vacuum hose....lol

I do aproach stuff with the mentality of it not failing in the first place but I also prepare myself for the unexpected. Do you carry battery jumper cables in your car?

Sure for the same reason. But you don't carry a coke bottle of gas around, do you?

[congerz83]

if nothing else you've shown there's no "magic bullet" to making a delorean reliable.

amen!

[Farrar]

...something everyone should bear in mind when working on one of these little beasts.

Bravo.

Martin, if I see you in Orlando, I'll buy you a pint.

Sorry but I've got no experience with nitro boosting so thats all Greek to me. I don't understand how an EFI system would suddenly be able to adapt to a hose with fuel in it. Would something need to be reprogrammed? I'm not trying to be smart, just asking a serious question.

No, I don't carry a coke bottle full of gas around with me. There is a coke bottle in my car that is half full of coke though. Hopefully after this weekend I will have about 20 bottles full of diet cheerwine as well. If I truely got in a pinch, I would be able to rig something up with a bottle, fuel line, and gas from the tank.

As I have said many times before, I choose to carry a spare fuel pump. I suspect my fuel pump problems to be ground related so last night I wired a ground connection directly from my battery to the fuel pump. I'm suprised no one has critisized this yet since I no longer have an inertia switch or RPM relay hookekd up anymore.

Lets wait and see if I have any fuel pump failures after 20+ hours of driving this weekend. If my fuel pump fails with with a solid ground connection, then we have a problem.

Originally I was going to be lazy and keep driving as is, without a straight ground connection, but I figure this weekend is an excelent chance to test my theory.

Bleh, diet? gotta go FULL Cheer!

What I was getting at with the ether is that all you need is a vacuum source to the intake (plenum) to run the engine. Sure, you are a lot better off with a carb (A/f control) if the pump goes out but you will only get a 1/4 mile or so out of it... I've never been that lucky when I run out and it's not very safe especially since it will run lean and be VERY prone to backfire when it runs out....not practical at all except in a very few instances at best. I can't imagine rigging up anything in a D with the tank lower than the engine...except like I said a lot of BS for a 1/4 mile trip.

I think I know what a lot of the problem is with carb pumps going out...we can check it out at the meet (I posted it some where before but no response).
