Fuel rail firewall side leaking gas?

[zukitrek]

I see that there is like hexagonal like part next to the end dome. Can this be unscrewed from there or the whole rail has to come out?

here are are all the parts, and all suzuki part numbers
part 13 on my car, was leaking it was the wrong part, not SUZ, and was to wide , some one used a generic flat copper washer off tractor.
the bolt there , interfered with that extra wide wrong part and caused the washer to bend , concave. and leak. (i had to get the washer fedEXP to me. fast)
I tried to find that very thin margin washer in all shops here, and FAILED. its way too thin (OD is very small)
using the correct parts, is key here.

part five 5, (yes hex) is the damper. and just unscrews. (CCW like any screw) Counter clockwise.
what it does not show here, is that the damper THERE, forms a sandwich, it hold the main fuel hose BANJO fitting
between 4 and 6 parts the BANJO fits. the FSM is the best source of facts here, we have it online, the 96 FSM is free, and shows all this under the rail pages.

suzuki uses BANJOS at ALL high pressure hoses. from here to the filter and to the tank, all rated near 100psi,
its not some carb parts, like on A samurai not at all. its high pressure.

the copper washers, have a critical OD and ID. (outside diameter and .....)
if the wrong part is used the parts, 5 and 3 will cause the wrong washer to distort. and leak.

read chapter 6e-3

this covers all this. pDF page 16 show the rail with all fittings !

see figure same page, C2-24 the man is removing the banjo fittings using 2 spanners, see that?
http://www.acksfaq.com/96-FSM-v2-6e3-c2-pdf.htm

this is the first step in engine removal this fitting, we do this first so it can be dry and stink free, benzene is carcinogenic.


here are the steps , on all MPI cars (rails)
1: reading the FSM, depressurize the fuel system. or you will get a bath infuel, if smoking , a trip to the grave. 60PSI is 60PSI.
2: then step 6e3 above. take off the banjo bolt cum pulsation damper.

here is my fuel safety page, the filter off is the most dangerous du to gravity and siphon possibilities.

that FSM covers most things on your car, but not OBD2 parts.
but the engine and rail and TB are the same. as is injectors.
the newer car has new electrics OBD2 systems.

This just great. You see the leak is in the inside/outside part of the end dome flat area. Just yesterday I swiped my finger again and it stained in red. Nothing leaky or runny, more like gunky? But yes it is a leak.

Ill tackle this on the weekend. BTW got all my parts for the ignition tune up: Bosch rotor and wires and Autolite Platinum plugs. Cap was replaced in summer. Thanks again!!

the red is fuel dye.
to be red like that takes a long time, or leaks all time and evaporates 1000s times making it red.
its a totally bad sign, fuel dye signs
but looks like back in the days of carbs and the carb was red all over... from that and the tetra-ethyl lead.

well like you said leak was getting worse and turning key on to do all the relay and combo switch tests i noticed a strong fuel odor. It was coming from that same part as the pump prime the rail every turn of the key. My leak for sure is from either the red arrows in this picture. Also no fuel is suppose to come out of that hole (green arrow) and what is the purpose of it?
   

Can I JBweld that lip where the lower red arrow is pointing to?
I see no other way of solving until monday?

In the next picture There are no leaks in any of these areas where arrows are pointing

   

I don't think is coming from banjo side either?

[zukitrek]

Found the problem doing some research as that hole was kind of odd. It happens that there is a screw that goes in there!! What happened with the old one? Who knows? Lets see what I can do.

the unit in your hand is bad.
its called the fuel rail pulse dampener.
suzuki sells it, do you need a part number , have it.



that unit has a spring inside and a Diaphragm, that diaphragm is cracked inside, end of life. there is no missing screw, im sure that is a factory test port.

i do not know GM p/n nor if they stock it. (i looked and could not find it, call them?)

suz. 15750-82400

i had to use Double crossing parts to find the trail of truth. ( typical suzuki parts buying,)
ok i searched the www using google and the p/n
and wells makes it for less. as does SMP
http://www.mypartsgarage.com/wells-fuel-...fd400.html

FD400
then i searched for FD400s;
and found out that rockauto does sell it, and is clueless, (typical) that these Fit all J18 engines, not just Esteems.
the proof is here
AIRTEX / WELLS Part # 3G1043 {#1575082400, FD400}

here is rocks link ( but its missing in G16Bs) an ERROR on their part.(no pun)
http://www.rockauto.com/catalog/raframec...ttype=6120

seems SMP makes it too for even less.
FPD66

btw 2, all these dampers fail just like that, they leak ,as do all Fuel pressure regs on the rail, all fail. about now.

i think rock has the best price. but do google it.

here is an odd fact
the part, is not used on the J18 suzuki sidekick sport, with same J18 engine.
but is uses in the same engine, in the Esteem. and same partnumber up to 2002
and is engine code 2 on the Esteem 1.8L

the odd thing is Rockauto, does not know it fits all trackers and Sidekicks with G16B engines.
amazing.

the engine that dont have it , the damper is in the fuel pump.

i upgraded my hard to buy parts page with this part.
it is.

[zukitrek]

So no screw goes in there? I swear one does, by looking at this part I found on oreilly, just for reference.
Ok I will look and see. Thanks as always. I posted some findings in my turn signal issue, hope u got to read it.
Will this part make my MPG suffer greatly? I mean Ive noticed that gas barely lasts under normal driving.

Good day sir

Look at this.
   
But anyways literally I'm screwed!!

There is no way for me to find that missing screw. How in the hell this happened? Oh well.

Look at this, from Suzuki

http://www.suzukicarparts.com/parts/1994...eid=214820

If it is OEM the price is not bad, compared to the other 2.

the screw sets the rate of dampening
its a factory setting , it is not a fuel seal, at all,its for calibration and for testing in the factory, the screw is not to be touched. period.
if missing that means someone was mess'n with it.
the diaphragm is bad
what else needs to be known?

a cheaper cars like toyota and vast parts support
this part is about 45 bucks.

almost all parts on Suzuki are 2 or 3 times higher,
the TPS is like $30 on my jeep
and over $200 on stinkn suzuki.

[zukitrek]

No hacking whatsoever even if it sounded like that, my idea came from observation and ignorance. I see online pictures with a screw then I see my part no screw, well, what would you think if you saw this without knowing? The same as I did. But heck lets just get the part and be over with.

Suzuki then would be my choice comparing the price difference is not much being it an OEM. Ill let you know how all this ended up. Hopefully well.

Good day sir.
