Does a 87 ranger STX, 4x4, with a 2.9 engine, use two fuel filters or just one??

A posting I was reading, before, was saying that some Ranger's have two fuel filters, the primary one and, sometimes, another one, in what's called the fuel accumulator..

Does a 87 ranger STX, 4x4, with a 2.9 engine, have a fuel accumulator as part of the fuel delivery system??

And if so, where is it located??

It should have an acumulator

trace the fuel lines from the tank to the inner frame rail uneath the drivers door.

you will find a canister with both send and return lines attached. Next you will find the HP fuel pump..then an in-line fuel filter just before the fuel line goes upward to the left front wheel well/inner fender. Some say the accumulator may or may not have a fuel filter...do a search here you will fine much to say about this situation...good luck

my 87 has one, my 88 has one..they are common to rangers & b2's w EFI...

There is also a filter in the tank, but it's called a "strainer"

Agreed
the only ones that might have 2 filters were early 86'....thinking that if the one in the reservoir/accumulator was a mistake at the factory....IF...there was one on the rail after the HP pump. If there was not a filter on the rail then you have one in reservoir/accumulator. to repeat 86' was prolly the only year that happened.

and yes they all have a strainer in the tank

I replaced the in-line fuel filter for the High Pressure fuel pump, before.. When I took it off, I wasn't even able to blow through it all..

You mentioned that your 87 has one, and you 88 has one and they are common to rangers & bs's w EFI..

Is this the canister that you were talking about, in your reply to this posting, which is the fuel accumulator that had fuel filters, inside the accumulator, on your 87 & 88 Rangers??

It sounds like all 87 Ranger's with a 2.9 engine with electronic fuel injection has a accumulator on the fuel system, whether mine is designed for using a fuel filter inside of it or not?? Is that a correct assumption..

If that is a correct assumption, and my fuel accumulator is designed without using a fuel filter, inside.. Is there anything else that can go wrong with them, that you know of, that I should check for??

Whatever design my fuel accumulator is?? Are they all made to come apart and do they all have a check valve inside them, that could cause any problems, or a filtering screen of some sort, if my Ranger's fuel accumulator happens to be designed without using a fuel filter inside of it??

I am currently in the process of cleaning my whole fuel delivery system, and my I took my fuel accumulator apart. It didn't have a filter, but was full of crap. What I did find is that the rubber O ring on the check valve was laying in the bottom of the bowl. I replaced it, but don't see anything else that can go wrong. I recieved my new tank yesterday and am going out in a few minutes to start putting everything back together. So to answer your question, no they dont all have a filter in the accumulator.

Yes they all had the same basic design....
fuel accumulator and canisters are one in the same.
Yes they come apart....the bottom bowl unscrews

86' version had a shorter bowl, they had filters in there.
87> had a bit taller bowl...they did not have a filter

How did the rubber O ring come off the check valve, that you mentioned was laying in the bottom of the bowl?? Was it split apart and fell off??

 

[xploridaho]

It was stretched out for some reason. Wouldn't stay on, so went to the parts store and got a new one.

 

[piotrsko]

the big black O-ring or the little gray one for the check valve?

took mine apart, found the check valve plugging the inlet, filled it with JB weld so now the return just goes to the tank. it still seems to accumulate, but only the pump inlet. I am thinking of replacing it with straight runs of fuel tubing.

EFI Rangers '85-88 have the "reservoir".

The Accumulator in '85 (2.3) and '86 (2.3 & 2.9) have a filter inside the
"Reservoir"

'87-88 do not, they have an inline filter (FG800 or equivelent) up against the engine crossmember

DO NOT ATTEMPT TO REMOVE THE COVER on an an '87-88 Reservoir,
there is a high order of likelihood that you will NEVER reseal it after doing
so and will have a massive fuel leak until you replace it.... as an assembly.

The paper filter element made for the "short" reservoir cannister used in
'85-86 won't mount properly inside the "short" reservoir made in '85-86


the Reservoir prevents momentary loss of fuel presure while braking,
turning or accelerating when the fuel level in the tank is low.

Darn, NOW he tells us.

OK, I took it apart. fixed it like I stated above, pressure tested it in a bucket of water (75 psi). I think I'm good to go, will report the results when I run it.

 

[AllanD]

Since switching to a 4.0 myself I don't look in on 2.9 topics as much as I probably should...

[piotrsko]

OK new filter, rebuilt accumulator, got fuel flow and pressure out the wazoo and no leaks.

runs for 5 minutes like a raped rabbit, then acts like it is lean.

AARGH

According to your information, no wonder there wasn't a filter in my accumulator when I took it apart..

It wasn't very much fun trying to put it together, again, either..

The large o ring didn't want to stay in the bowl's o ring grove, until I carefully stretched it out enoug it to stay in place, in the grooove, until I got the accumulator's bowl screwed on, again..

I remember reading, before, someone mentioned that there is a check valve in the accumulator with a o ring on it.. Do you know if that was a correct statement, or not??

I didn't notice a check valve in my Ranger's accumulator, when I had it apart.. I was wondering if I might have overlooked it, incase it is designed with using a check valve??
