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

[stevedmc]

If people are converting to carbs because their K-Jet is being a problem, do any of them check the state of the tank?

Yep. A previous owner cleaned the tank, replaced the K-Jet fuel pump, replaced the accumulator, and who knows what else. I don't have the records in front of me at the moment.

Perhaps my car already had electrical problems at the fuel pump. What people don't realize is my low pressure fuel pump has less problems than my old CIS fuel pump, even with suspected electrical problems. Hmmm.

Our fuel pumps only have to run long enough to keep the carburetor bowl full. The fuel pump could sputter on and off all day long and it might not even be noticed because we only need it to run long enough to fill the bowl. If a Kjet or EFI fuel pump starts to sputter you are screwed.

Not necessarily -- remember, those roller-cell fuel pumps put out more fuel than is necessary. It would be possible to run the engine with the fuel pump at less than 100% efficiency, but you might occasionally stall under load/acceleration, or get other symptoms of a lean condition.

Hmmm. I'm amused.

Somehow the carbs vs K-Jet debate has segwayed into "Carb conversions vs EFI conversions".

do any of them check the state of the tank? It might explain this rash of pump failures... I reserve the right to snigger if this is the case,

Mine was cleaned twice. Eventually we wised up and ditched the metal bracket.

I have a feeling Martin's sniggering, anyway. ;-)

That or he is possessed by Steve.

[DCUK Martin]

Nah, not really. Despite Bill's efforts to make it look like the contrary, I've never suggested people shouldn't convert to a carburetor.

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

Can you run EFI or CIS with a coke bottle full of gasoline?

Tell me something I don't know. I used to cling to 'but it's thirty years old!' I don't know why I ever made that argument.

Sure! If there is a way for the air to get in, I can get fuel in..??? But you know...

Seriously, tell me why you seem to approach a lot of this from a 'build/fix it for when it fails' rather than for it 'not to fail' in the first place? -- No BS, sarcasim, wit, etc...straight up?

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.

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?
