Trouble starting; fuel injectors, fuel filter, or fuel pump?

Recently bought a 2007 vtx 1800R. It's got about 14k miles. I bought it in Dallas, and before I rode it to San Antonio (5hr ride not including traffic and stops) I did some upkeep. Changed out the spark plugs (which looked like they hadn't ever been changed), air filter (which was pretty filthy), cleaned out the throttle body, sprayed B12 cleaner into throttle body while the bike was running, and ran a can of Royal Purple fuel cleaner over the course of filling a few tanks.
I was planning on changing out the fuel filter now that I'm back home, but I can't find anyone that sells them without the pump.
*So that's the first problem. Anyone have any info on where I can buy just the filter?
The other is that it hesitates starting, and at times won't start at all at times till I spray throttle body cleaner into it. Do you guys think this will be resolved once I replace the filter, or do I need to plan on cleaning the fuel injectors as well? If so, I haven't seen any good info on how to do the job on this bike. I also have a 04 vtx 1300c, and I've cleaned out the carburetor after it sat a good 8 momths while I was out of town for work. That came out well. But now I need to become more familiar on the process for a fuel injected system.
Suggestons please.

Never, ever spray carb cleaner into a throttle body especially when they are coated with molybdenum paste for protection. That wasn't dirt, that was the protective coating and when people have done the same thing you have done, had to replace the throttle body to get them up and running again.

Fuel injectors clean them by running a bottle of Techron Fuel system cleaner through the bike. Split a 12 ounce bottle over 2 or 3 tank fill-ups, do this once or twice a year. Techron is recommended by Honda and many other vehicle makers for this very job

Spark plugs, should be good for 100,000 miles. Just take them out once a year and gently clean them with some Techron and a toothbrush and put them back in

fuel filter... should NEVER NEED to be replaced... if clogged.. fuel tank is full of crap..


if true,, injectors are trashed. improper storage of a fuel injected vehicle is not a good deal. my opinion.


if the plugs you removed look bad.. injection system and fuel have been BAD for sometime.
as Mr Spike stated the spark plugs are 100,000 mile plugs...
and under normal use WILL last that long. mine has 74,000 miles on original spark plugs..
I got my bike NEW in 2005... inspect plugs every year.

On the Front Ignition coil mounting bolt is the "Common Electronics Ground" lug.
Clean the lug with 5 wires on it. Three wires are dedicated for the ECM.
Details on this are "Ground Fix" in the 1800 Step x Step board.
You may want the disconnect and reconnect some sensors.
Camshaft position sensor on the front left cylinder(I believe).
Controls Ign timing to some degree.
