Fuel Guage 01 cummins
 

Ive got a 01 cummins 24 valve and my fuel guage quits reading at half a tank...any idea what the problem is?

Try banging really hard on the side of the tank and see if you can dislodge the float. Sometimes they hang up

ive tryed it it doesnt work

Mine crapped out and ran out at 1/4 tank.ordered a sending unit and drawstraw to compliment the raptor 150 pump I installed.just make sure you index the fuel module in the tank right or the float hits the side of the tank and sticks(don't ask how I know):w2: if you need the part # for the sender only let me know,I've heard.some parts guys try to sell you the updated module with intank pump.

YUP, i found that out the hard way.... stranded on interstate....out of fuel, the day after i bought the truck. I used a new Airtex Module my buddy had just bought for his 03 and didnt end up using, took the pump out and added the Vulcan DS-V, works like a dream.
If you dont want to mess with the 2 different parts, Vulcan sells the "Modified Liberty" Fuel module that comes with draw straw already installed.
Modified liberty fuel module

so in other words im gonna have to drop the tank?

I dropped the tank and it was easy,but some people say its easier the lift the bed.

whats a draw straw?

The drawstraw is a larger diameter pickup for the fuel tank.when you up the power and demand for fuel,it helps with fuel flow to the vp$$ pump.

allright i gotcha.... i think id rather take the bed off... that way i dont have to run it out of fuel.
