Where is everyone #5

I would think that has more to do with the delivery system than the fuel. In effect the direct injection system gives a very well controlled amount of fuel as opposed to a carburetor, which we all know can vary widely on the Air/Fuel ratio due to vacuum leaks and jet sizes.
But the duration of the squirt of fuel through a tiny hole is so much more exact. The only real variable is how long time wise is it squirting.

Edit.
Took me so long to type that y'all had already covered this.

 

I had a Jd 7520 with a 531 that loved to loose it's prime if it sat for any amount of time. With the tanks sitting down low on the frame it was like trying to get a reefer going that was ran out of fuel. One small electric fuel pump and never had a lick of trouble again.

 

This is why in the older days most company and ltl drivers had vise grips if they drove a cummins and PT pump. In a calculated adjustment pinch off the return line to cause a back up and raise fuel pressure in the injectors. It was what they did driving castrated trucks and getting paid by the mile.

 

All modern fuel injection runs about the same. Constant supply and return the unused fuel. There was a few return carb. systems. Never took off very well in mainstream. However there has been some hot rodders make it work well.

 

Nope, back the timing off and burn more fuel, with more boost. With in reason.

 

Don't be trying to bring reason into this discussion. We got rules you know ?

 

@Oxbow @rank if you guys do decide to fix you up a electric pusher pump set up, you can do away with the primer pump and either put a bypass plate on the filter base (CAT# 6N-4414), or get rid of that entire filter housing assembly and mount a secondary fuel filter base in its place to get away from those small restricted ports.

On both of my B models thats what I did and made things pretty simple that way. Keep your fuel press at the injection pump around a heavy 45 psi and you'll be in good shape.

 

Rank, black smoke is from late fuel delivery. Most of the time close or after top dead center and its burning in the manifold or turbo. Black smoke is a waste of fuel. White is unburnt fuel. Puff of black between shifts is rpm, timing change, no concern
So we aint sled pulling lets not compare the two. You wanna impress me, let me see you make that power and burn clean. Thats cool to me.

 

Sorry I forgot were I was.

 

sal'right , just don't let it happen again.
