broke down, again!

[deejaaa]

in the cab of a tow truck. same thing yesterday. thought it was the lp, gauge showed zero pressure. changed it, was t it so changed filter. pressure showed 7. all good, i thought. drove in this morn, 45 miles down the road rpm/speed starts falling. made it to work, max speed 20. drovt to flaps thinking it was the ip screen. removed everything to get to it and it was clean. no strange noises/vibrations. at a loss and am very discouraged.
think i will count my losses, lick my wounds and pull the 6.5. try to pull funds from my arse because i dont have any extra. gonna sell extra parts and get either a 4bd or 4bt. dont need to tow a lot but like the room and ride of the 4 door.
if there are problems with my typing its because this ford wont stop bouncing.

tank sock?

It is that masked man in your avatar sabotaging your truck. :rof:

That sux, riding in a ford makes it a double whammy. :agreed:

Wish you luck on what ever your adventures take you. :thumbsup:

 

[deejaaa]

oh, this is the 93.

 

[deejaaa]

tank sock?

crossed mind but getting good flow from tank.
avatar might have cursed me.

 

[ak diesel driver]

is your pressure guage permanent or just temp.? also are you reading your pressure prefilter or post filter?

 

[deejaaa]

pump is perm. located post. do you think it might be reading total pressure instead of lp pressure?

 

[Pillow]

Hang in there! It has to be something fixable.

Any codes?

 

[deejaaa]

there is no controls on the engine, it's mechanical. TCM(trans) has been overrode and has full manual control.

 

[ak diesel driver]

so to recap you have a fixed pressure guage that when you start to have trouble it shows that your losing fuel pressure?

 

[Raleigh]

Pressure does not mean volume. Check the sock and all the screens.

it did 2 days ago. after i changed LP and filter, it shower 7 psi. it was reading 7 all day today, even when the rpm's were dropping.

 

[ak diesel driver]

I would check that IP screen again. maybe you have a hose deteriorating from the inside

.....................thinking it was the ip screen. removed everything to get to it and it was clean. ................

in my first post.
in the 5th post, states i am getting good flow from tank.

 

[ak diesel driver]

and your positive your guage is post filter?

 

[indybeck]

Do a volume test, had 6.5 PSI, and very little flow. Heath had me do a flow test, and volume was next to none. Should have around a gallon in 1 min.

How cold is it there? The symptoms are sounding a lot like what I'm dealing with in my '94, In my case it was gelled fuel.threw in some Diesel 911 and let it sit for a day to let it reliquify the fuel.

Sock problems can be intermintent. When the truck stops the crud can be dislodged from the sock til it gets sucked back again.

I always run about a 1/2 gallon of fuel out the drain into a clear jug - I use a one gallon pickle jar. I note the flow while looking for crud or whatever while pumping and let it sit for 20 minutes or so and look for water bubbles.

I have had just running the fuel out the drain clear up my problem.

I always double check a lift pump when changing. Often I will disconnect the out side of the pump, run a hose to a container and note if the flow is the same as that out of the drain. If there is bad flow I pump from one container to another to see if the lift pump works off the vehicle. I do all these steps because I've been burnt by not doing them at some point in time. Switching parts without diagnostics gets expensive

Always use an Ac Delco lift pump if going OEM style

jrsavoie, thanks for the step by step. i will most def do that but unfortunately we have plans this weekend and next. seems like every day off i am working on one of my trucks. other things are getting neglected and the wife is losing patience.
weather is in the 70's.
sock is suspect #1 so i will check flow and volume.
thank you everyone for the responses.
AK, i will double check whether post/pre FFM.

 

[deejaaa]

started draining the tank. going to drop the tank. it's full so this will take a while.

using the old LP, kind of slow..........
each container is 15 gallons.
fuel is pretty clear for being 60% veg oil.

already decided to remove the sock and make a sump on the tank.
can anybody guess what this pipe is? i will be using this for the sump.

it's thick enough to weld to the tank with a feed fitting. will cut/slice a section, flatten it and weld it for the base.
