You have to have a 7.3 style filter head. That filter won't work on your 6.9 style.Can I use that fuel filter on my '87 6.9 n/a that doesn't seem to have a water separator anywhere?
Yea the lift pump is bad I think. Truck stalls of deceleration. If allowed to come down slowly then truck stays at idle. I bought the truck last December. Hadn’t replaced the fuel filter yet so figured I’d try that first. Filled up with atf, drove it about 4 miles last night. Didn’t see improvement. Gonna replace lift pump today. Light comes on dash at start up, but is never on any other time so I would guess not.That is a bunch of water. Only time I see that much is if a person has gotten a bad fill up causing the truck to run rough. Did you change it for a reason or was it just time? How many months/miles were on it? Do you still have the filter vacuum light and is it operational?
IMO, buy 2 filters, install one and put the other in the cab as a backup. Then add a bottle of clear diesel from power service to the tank.
Correct but you can’t find that part anywhere. This is what came when I bought it.I know a lot of people hate them, but the 2 piece filters with the clear bowl are nice for this reason. You'd have seen the water plain as day when you opened the hood.
There is no drain on the bottom of the tank.If you use an additive that will disperse the water it will place the water in suspension in tiny droplets - untreated diesel fuel will leave the water on the bottom of the tank where you have a chance of draining the water out rather than the entire contents.
I'd like to put a water separator back in my ('87 6.9 n/a) system also.My 86 had the water separator on the Fire Wall that is prone to leak, Was all ready bypassed long before I bought the truck.
I replaced it with a Racor 500FG in it`s place with a 2 micron filter. Has a large Bowl on the bottom that can be drained.

If your original water separator was bypassed and the steel lines were left alone, that would be a good place to hook into the line. Originally, there was two steel lines that both pointed up toward the separator. The easiest way to bypass it is to run some rubber fuel line between both steel lines. If this has been done, it's as easy as removing the rubber bypass hose. In case you didn't know the stock separator is underneath and of the master cylinder.-Where is a good place to split the fuel line?
