Engine won't start out of fuel / Low fuel level in Racor on a 6v92

This is one from the should have know better department. My PO told me whe the fuel gage was on E that I still had about 50 gallons of fuel. Foolish me belived that, so now the bird sits in the yard with 30 gallon of fuel that I have put in. How many more 5 gallon can do I need to put in it before it wil start? I haver filled: the Racoc and lossened the fuel lines on top of fuel filter. I have another 15 gallons that I can put into it.confused:d

that should be plenty Hugh!
spin the engine until fuel comes out the lines on the filter,tighten the lines,hold the go fast pedal to the floor and start her up!
save that other 30 gals of fuel,i'll pick it up at the rats!

Isnt there an electric pump (facet?) that should prime the system if you turn on the ignition and open a fitting?? Ive wondered about this, it should work for changing the racor too...??

Or am I missing something...??

Thanks, Joe

no electric pump on a detroit powered coach.
Hugh,did it run out of fuel at home?

Yes Randy it did run out at home. The 30 gallons was enough. I filled the racor, will replace it in the morning(before the GA state bird wakes up and thinks I am a food source for them) replaced the fuel filter and cracked the lines like everyone suggested. lesson learn when the genny stops it is time to start looking for a place to get fuel. Randy I think the rest of the fuel will be in the tank by the time I get to Rats. I be glad to loan you my cans.

keep us advised Hugh,good luck!

I learned last year (when I replaced mine) that the little fuel pump on the 6V92's is not self-priming. I had to pour diesel down into the pump's supply side until the line overflowed and then reconnected it to the head on the secondary fuel filter. With the primary and secondary filters topped off and the fuel "in the lines", mine cranked and started pretty quickly.

Oh yeah- one more thing-- our fuel tank can be pressurized with compressed air. If you leave the fill cap on the tank and disconnect the fuel line that feeds the Racor- use a rubber-tipped blow gun and slightly pressurize the fuel tank through the fuel supply line. Usually, the fuel will begin to flow as soon as you remove the blowgun from the end of the fuel line. It does not take much air to accomplish this. Usually, you will hear a "thump" when the pressure in the tank exceeds the surrounding atmospheric pressure.

Just a question, the WLSP 36 has a facett fuel pump. There is a button labeled PRIME on the rear starting panel where the switch is showing FRT--OFF--REAR.
In the event of running out of fuel , would this pump prime the system enough to get started after refueling? I wanted to simulate this at my Cat Dealer shop, but he said NO WAY to my test proposal. Oh yea, my fuel LO WRNG lite and the buzzer start at a little below a 1/4 tank. I found that I have still at least 40 gallons left, (my lowest ever) BUT next truck fuel stop is mine. (my tanks is 200 gallons, my fuel range is about 1400 miles, and my limit I use is 900 miles max.)
Flying-J here I come.
