Archived FASS problems ....diesel dan help....

i just got my new replacement fass 150 pump and after installing it i dont have any fuel at all



i unhooked the line going into the injection pump and then bumped the starter and i dont get anything coming out of the line at all





the pump is making noise



the fuel filter is full



the water separator is full and if you open the bottom it will syphon fuel out of the tank

Do you have a fuel pressure gauge in the line?

 

[Mopar_Tim]

yes i do and i unhooked that too and tried to bump the starter with and without it connected

 

[p-Bar]

Do you have good pressure once the system is "pumped up" ?

 

[Mopar_Tim]

i cant get it to pump up at all ... . i cant get it to move any fuel ... . i took the line out of the injection pump put it in a bucket and bumped the starter ... . did not even get a drop out of the line from the fass

Did you try loosening the filter while the pump was running?



When I first instaled my 150 it would not pump until I loosened up the filter to get the air out. I almost got a fuel bath when it kicked in.

 

[Mopar_Tim]

no i never tried that i will give it a shot tonight after work

Did you put the ball back under the T-block?

Without that ball... . you will have no suction or pressure. That is the most common issue i see with folks in your position.



Definatly try cracking the fuel filter loose and run the pump (Make sure the water separator is tight). This will bleed the air out like said above and some pumps are stubborn and will not run unless you do this first. IF this dont work, go on below.



Remove the water separator and crack the fuel filter loose. Run the pump. See if you have suction. If you dont, i would remove the t-block and see if the ball is in place or not. WHEN You have the pump off, run it. Check for suciton at the small port. Put some oil in this port as it will help with pulling fuel and keep the gear happy.



I will PM you my personl cell number as we are going to be leaving here shortly and i dont have Internet at the house yet.

i pulled the t block back off just to make sure i have got the ball in the right spot it is in place ... . and the o rings are good to go also



since i have got the pump/t bracket off i will try and run it now to see if i have got pressure

 

[Mopar_Tim]

ok i tested the pump and i DO have pressure guess i will try what you said above and see how it goes

 

[Mopar_Tim]

i put the t bracket and pump back on, left the fuel filter off and bumped the starter, after about 10-15 sec i started to get fuel coming out of the bottom of the fass ..... put the fuel filter back on bumped the starter and got an instant 13. 5 psi to my gauge ... cranked her over and she started right up and is sitting in the driveway idling right now, i dont know what i did different this time vs the last time ..... but on the same hand i dont really care b/c its running


thanks a bunch dan

Good deal glad you go it going.

Like I said with mine it did pump but very little until I loosened the filter and bled the air out and then fuel everywhere.
