"To do a pressure test is that a dead end test or a in line test ?"
In line.

I need to get a service manual...
Worth their weight in gold in situations like these....well silver anyway.

Either way will give you the answer. If you can hear the fuel spraying in the tank, I think you found the problem.

Pressure test will confirm it, inline test with engine running, increasing throttle would be the better of the two tests. Dead end will show it not holding pressure after pump cycles.

Now to find a tester that hook to bike. Might be able to adapt my car tester. I can see it spraying in the tank in a fine mist and some bubbles

but at least I think I found my problem

No point pressure testing it until after replacing the hose/filter in the tank, the a road test will confirm the repair, no pressure test needed.

Probably right I'll know right away

If it spraying it's gotta be fixed.
So it all has to come out.
Then it's gonna be right in front of you , hose ,fitting regulator etc.
You might as well change the filter at this point also since it is out.
You won't really need a pressure gauge. Like said a road test will tell you
But if you want to adapt your current pressure gauge ?
You can save the coupler off the old hose (if the hose is bad ) that gives you the female coupler. You will have to buy a fuel rail hose from Harley to get the male end .
That gives you both male / female couplers . Now you can adapt you current gauge.
Or a 39.00 harbor freight automotive pressure gauge can be adapted fairly easy

Took the pump assembly. Out this morning looked it over and can't find a thing no place where its rubbing no holes that I can see. There are some tight turns on the lines might be a fitting but dint know how to tell for sure .
I took the filter out looked OK so I blew back threw it by mouth (yuck takes me back to when I was a kid sucking gas out of my dads tractor for my dirt bike

) and it seemed open some pressure to do it but not a lot .just not sure what to do next ?

OK I put the pump unit back in but held the filter unit up a little so I could look at the fittings and lines and the fuel spray I see is coming out of the small hole in the back of the regulater is that normal I have no idea

IMHO, as others have said, if you can see fuel spraying around inside the tank, them you need to replace the lines in the tank.
I have an '03 FLHTI, and the interior fuel feed line was longer back them, which caused the rubbing and the leaks. The newer model line is shorter and doesn't have the same amount of "play" so it doesn't seem to get rubbed causing the leak.
Replace the interior lines and fuel filter, and use the old lines, split lengthwise to wrap around the new ones as "insulation", hold em in place with ty-wraps.
Did mine a few years back and have had zero issues with fuel leaks since then.
Also, get the shop manual, definitely worth the investment, it'll tell you exactly how to go about doing the replacement.

With the filler,filter housing pulled up a bit I can see the fuel spraying out of the back of the regulator there is a small hole there I seen while I had the unit out.is it there to bleed of excess pressure or is the regulator bad ? I know that is where it is coming from.

IIRC the regulator has a hole to keep air pressure equalized. If fuel is coming from the hole the internal pressure diaphragm is bad and pressure dropped causing excessively lean running, hence the lack of power.

That's what I thought in the auto industry if the reg. Is leaking fuel its bad but there not in the tank so I wasn't sure. Thanks guys for all the input and putting up with me and all my questions.

ron stombaugh · « **Reply #38 on:** Sunday, September 16, 2012. 10:20:40 AM. »

I thought for sure the reg was the problem but not sure now I was just reading online how it works on a 09 and it said the reg is in the tank and returns excess fuel to the tank so I'm thinking the spray in the tank maybe normal . If my reg was bad wouldn't my pump run longer if the pressure wasn't building right ? So I think its time to look at something else

FLTRI · « **Reply #39 on:** Sunday, September 16, 2012. 10:30:57 AM. »

Until you measure the pressure it's just a guessing game IMO.

I would love to check the pressure but I looked at my lone coming out of the tank and it does not come of bothends of the line are press fit on the tank fitting and the throttle body . So there must be another way to test it

strokerjlk · « **Reply #41 on:** Sunday, September 16, 2012. 01:05:53 PM. »

You have to have the fittings i was talking about.
Imagine what you need... You unplug the disconnect from the tank , couple that to your gauge, then couple the other end of your gauge to the tank.
So you have to have both couplers . Buying a guage for a Harley is high dollar .
It is cheaper to just Buy the two parts (lines) from Harley, and use the couplers and throw the rest away

ron stombaugh · « **Reply #42 on:** Sunday, September 16, 2012. 01:20:55 PM. »

Only problem there is no disconnect fitting . Just looked like a petcock looking deal with the hose pressed on to it

FLTRI · « **Reply #43 on:** Sunday, September 16, 2012. 02:37:05 PM. »

Ron,
It works just like an airline fitting. Push up on the chrome sleeve and pull down on the fitting.

Out OK had no idea thanks damn I gotta get a manual

ron stombaugh · « **Reply #45 on:** Sunday, September 16, 2012. 05:59:30 PM. »

Put it back together and took it out for about a 60 mile ride ran great the whole ride. So either it just didn't do it this time or I had a connection leak in the tank and by taking it apart and putting back together sealed it up don't know time will tell I guess. Still getting some fittings to test my fuel pressure though
