...when a fuel pump (lift pump) is pumping fuel? Lots! I found out today afer draining the cannister for the first time since 0 miles. I normally drop in a new filter and go. But today, I saw lots of sediment at the bottom, so much so that I actually had to break out the vacuum cleaner to suck all of the grit off the bottom that paper towels wouldn't pick up. So after cleaning, I had installed the new filter and positioned it above the cannister and had my wife bump the starter. I figured if the cannister was filled before I tightened the lid, I could prevent air from locking the fuel line to the IP. Before I could react, the cannister had filled and fuel was pouring over the top. Hearing me yell...well actually swearing, she had the good sense to turn the key off. What a mess! That's one trick I won't be pulling again. At least I came away knowing the pump is still in good shape. Oil Dry is a wonderful thing.

 

Last time I changed it, I tightened the lid about 2 turns and did the same thing,
thinking it would accomplish the same thing, getting the air out without pushing it into the lines.

One bump of the starter, and turned the key off after bumping.

By the time I could get around the open door, fuel was squirting (under pressure) out around the threads.
Felt like a half gallon before I could get the lid tightened down all the way.

No air though, started up like I never changed the filter.

Engine probably a little cleaner as well, wonderful degreaser that Diesel stuff.

I was trying to copy your technique as I had read it recently. I figured with the wife in the cab, I'd have no problems, so I left the entire lid off. I could barely tighten the lid down there was so much pressure.

 

I did something simular... I clean the bottom of the canister and closed the lid and bumped the starter and waited... Well there was only about 3/4" of fuel in the bottom when it finished running the pump. Well I figured I would pull the top off and rebump... Bad idea the pump filled the canister fast! Turned the key off and the pump ran on for about another 3-5 seconds! What a mess!

Next time I'll do it on the dirt roads not in the middle of my shop!

 

Oh the joys of owning a diesel!

 

 

Re: How much fuel should a fuel pump pump..... If a fuel pump could pump fuel??

 

LOTS

 

You beat me to it, but I'm gonna add to it.


A fuel pump would pump all the fuel it could pump, if a fuel pump could pump fuel.

 

Its real nice having a schader valve next to the sending unit of the FP gauge mounted at the highest point in the fuel system. Makes bleeding air out real easy.

 

You should see how much my PE pump can pump at 20 psi.

 

So nice knowing I'm not the only one who uses deisel fuel to clean the drivers side of the engine, shop floor, and anything within 6 feet of the canister. Good ol' dry sweep

 

My Ex girl friend hated theact that her cat's fresh litter bag was always just a hair shy of empty.

 

My 2 year old driveway is in the process of disolving! I came home today to find my big Michelin tire print right in the area of the spill. The asphalt is very soft and appears to be melting from the fuel. Never a break....never...

 

Yup, Asphalt and Diesel don't mix.

That's why just about every gas station has concrete pads around the pumps.
