Engine runs , fuel pump don't

[tco3129]

Noticed no hum coming from the fueltank so I checked it out. I got no (like that " got no " yeah I'm a hillbilly ) noise from the tank, no aggitation and no squirt from the primary fuel drain. My question is How is my engine running?
I am running 60% WMO 40% diesel and fuel conditioner. Again HOW ?

the IP will suck it through, might not make full revolutions that way though.

your truck has a working IP injector pump on the engine . till you get air leek or run " low on fuel "
your ok.

Check the fuel pump fuse if you need more info or to talk to another deuce owner call me
810-Five 77 35two 4 call any time

also check the plug for 24v with switch turned on . then check that ground is ok. Its the wire from the frame nearest the tank .

hope this helps

 

[tco3129]

On flat ground ( hard to find here ) it will run against the gov and do over 50. Never driven or rode in another deuce but mine seems to pull the hills reasonably well.

Ditto digitaldust, check the plug on the pump, check the fuse, and check the ground. Typically the pumps dont go bad. They do fall apart and can be put back together, but don't go bad.

Good luck.

Yes, they go bad. Make no mistake.

2 out of the 3 military 6x6's I've owned have had dead fuel pumps. I just ended up replacing them with an external airtex fuel pump.

Check your fuse first and foremost. It's under that cover where the power cable plugs into the pump(tank).

 

[tco3129]

Thanks Digitaldust for the info I'll check it out.

The Gimpster speaks the truth.....I have replaced a couple of bad ones......the usual suspect is the fuse. It requires a slow blow one that ain't cheap.

The second issue is the bottom falling off the foot of the pump...some of the newer ones are rivieted in.....anytime I have to put one back together I always drill a small hole and secure it with a small self tapping metal screw.

Definately check the fuse. If your pump is junk, I have a brand new in the box one if you need it.

 

[Heavysteven]

Yep, check your fuse. Mine was filled with diesel seriously.

 

[tco3129]

OK, I checked everything out including pulling the pump. Funny, the pump will run upside down. Rattles like crazy upside down. It's trash. found new replacement for $151. Order it payday.

He's right, run out of fuel or air leak and your done. Game Over

If you can live with a pump on the outside of the tank, the airtex pump is only $70.

An air leak . . . as in, a pinhole in the fuel line and air gets in? Wouldn't that be kind of bad regardless of the condition of either fuel pump? Or an air leak somplace else?

 

[micmccon]

I was going to drain some fuel out of the fuel filter to investigate the extended crank condition that I've noticed on my Deuce. I had the wife turn the main switch on while I listened at the tank and I got nothing! I am soooo glad I didn't drain out the filter before checking this. I suppose I would have had a large green truck to tow out into the yard until I could bring my volt meter home to investigate the pump issue! The wife would have been pissed! Oh, well I can wail until Monday .

 

[srodocker]

anyone know the exact fuse i need?
