Fuelling

[Merk]

After getting the typhoon back from the dealer on the transmission issue, I noticed my truck was being a complete pig.

We're working with a stock truck here, btw.


Performed all the routine checks; everything checks out ok. Only thing lacking would be its probally due for PCV's (20K on current valves).

Slight smell of gas at start-up, with a puff of black smoke. Hello, Im running rich.

Hook up the FP guage, vac off, key on....HOLY COW...found my first problem. Im looking at 80 psi. Continuing on, I notice the needle dropping (bleeding, 1psi/3sec). Thats my second problem.

Hmm....just a bad FP? bad injector(s) also?

Whatcha think?

The 2 just behind this a few posts - "tranny seems to be on the way out", and the one about modding shift points.

i'd check the FP regulator. if its the stock one, just replace it. they are pretty cheap, and i'm sure tons of people have them laying around.

If Ur gonna replace the FPR, go w an AFPR.

Hey Merk,

What was done to the tranny? Any chance that they may have kinked the return line? That would explain the sudden rise in fuel pressure.

It has an ATR afpr, which i forgot to mention in my previous post. It's been there for a few years and likely over-due to replace with a full billet unit.

Thanks for reminding me BW

Tranny was replaced. It is a possibility, any specific area I should check?

If it is a kinked line, not knowing where the fuel lines go..if not the tranny, I did have the engine oil lines replaced as well. Anyone have an image of the line routing to share?

Thanks for the help, so far

You're the historical department and don't know where the fuel lines run????
:roll: Sheesh :wink:

I believe the manuals depict the fuel line routing. I am away from home or I would scan it for ya. Id take a close look as they probably lowered the tranny without disconnecting the lines and bent one. Otherwise that's a weird coincidence.

 

[sytyguy]

In a Typhoon the fuel lines go like so. The lines start at the sending unit, run over the axle on the driver side and tuck into the frame just after that. They then hug the frame until running thru the fuel filter at the crossmember. After that they make a 90-deg turn towards the tranny and join they're counterpart lines. From here they make another 90-deg turn (towards engine) and hug the tranny all the way to the bellhousing where they split. The return then goes to the bottom of the FPR and the feed goes to the fuel rail.

Hay Tony-

Would a kinked line not cause a decrease in pressure? I'm totally running rich therefore, Im getting fuel..just too much.

I'm going to replace the afpr as well as injectors..see if that helps any.

if your return lines is pinched that will make your fp go up. thats what your regulator does, you turn it downand it closes up the passage the fule passes thru.

pinching off the pressure line will probably cause a lack of fuel since there is less fuel.

Want to see this in action, Take a needlenose visegrip to the rubber lines in the fule syustem down next to your tranny were thelines make a 90 degree to go toward the tranny from the frame rail.


In this case they probably kinked the line where they bolt up behidn the motor or as they apss over the tranny, uless they kinked them at the rubber ends where they do the 90 degree turn.

Looking at the fuel filter you'll see the fuel lines run together and turn, with a mounting clip that attaches to the bell housing. Look real close at the clip and see if the lines are kinked. If I recall there is only one clip that attaches the lines to the bell housing.

 

[Merk]

Ok,

After close inspection of the entire fuel line...no kinks.

I've got my stock FPR in a box [somewhere] that I plan to swap out and see what happens.

Any more brainstorms, I'd love to hear them.

Keep you all posted...

Doesn't just backing out your adjusting screw lower the pressure (and also decrease the leakdown rate)?

Maybe someone at the dealership just 'played' with it ... as in "I wonder what this does?"
