On an Elite 3500 paint travels through the inlet screen 710-046, the 730-332 down tube and the 48-inch 0533906 siphon hose, then through the 730-067 manifold filter and the gun filter. A clogged screen or filter causes pressure loss, pulsing and spitting, so clean these first, before suspecting valves or pump parts.
The feed path
Paint on a gas Elite 3500 goes from the bucket through the siphon parts, into the pump, out through the high-pressure filter and on to the hose and gun. Pulsing or starved flow usually starts at the beginning or the end of that path, and both ends are quick to check. The siphon side is on the Elite 3500 Siphon Hose Assembly page, and the filter parts are on the High Pressure Filter page.

The Main Assembly page also lists the 710-046 inlet screen, the 0537231A siphon assembly and the 2366643A siphon tube. Use the page that matches the part you are replacing.
Read the diagram for how the pieces connect on your sprayer. As a general rule for any siphon feed, a loose clamp or a cracked hose can let the pump pull in air instead of paint, and that can look like a blocked filter. Titan does not publish a service life for any of these parts, so check them by eye instead of waiting for a schedule.
Strainer and filter basics
Airless sprayers use three stages of filtering: an inlet strainer, a pump or manifold filter and a gun filter. Partly blocked filters cause pressure loss, pulsing and spitting, which is also how a worn valve or a worn tip behaves. Because the filters are the easiest to check, they come first. Clean them after every job, and use the filter mesh that suits the coating you are spraying.
Strain the paint before it goes in the bucket. That keeps skins and grit from reaching the screen in the first place, which is easier than clearing a screen full of solids on the job.
High-pressure filter parts
The Elite 3500 high-pressure filter page lists eleven parts. The one most people need is the filter itself, 730-067, a 60 mesh manifold filter at callout 9. Around it are the parts that hold it in place:
- 2429835 filter housing, callout 11.
- 702-251 filter screen adapter, callout 7, and 757-105 filter support spring, callout 6.
- 9994245 pressure spring, callout 10.
- 9974027 PTFE O-ring, callout 5, 9970110 washer or seal ring, callout 3, and 0097304 washer, callout 8.
- 2365157 orifice, callout 1, 2429834 material feeding screw, callout 2, and 2429838 pulsation dampener, callout 4.
Titan describes the Elite 3500's vertical filter as one that keeps residue in the housing. If you take the housing apart to clean the filter, look at the O-ring and washers as you go, and keep the part numbers handy for anything that looks damaged. Relieve pressure with your manual's procedure before you open it.
Gun filters
The gun filter is the last stage. The Elite 3500 accessories page lists 0089959, a 100 mesh yellow filter, and 0089957, a coarse green 2-pack. We do not say which mesh suits which paint beyond the general rule that the filter must suit the coating. Check your gun's manual for how to remove and clean the filter.
Cheap checks first
Look at the inlet screen
Pull the siphon tube out of the paint and check the 710-046 screen for dried paint, skins or grit.
Check the hose and clamp
Look for a cracked siphon hose or a loose 103-679 clamp. Air getting in looks like a blocked filter.
Clean the manifold and gun filters
Clear the 730-067 manifold filter and the gun filter after relieving pressure.
Check the tip
A worn or partly blocked tip makes a coarse, streaky or spitting pattern.
Then look at the valves
If everything above is clear, the pump-side valves are next. The outlet valve assembly page and the pusher stem assembly page list their parts.
Ordering from the diagrams
Open the page that matches the part, find the callout and add it to your cart. The 4500 has a separate siphon system page that lists the same siphon hose and down tube numbers, but order a 3500 from the 3500 pages. If you are not sure which page holds your part, call (713) 931-0006 with your model and serial number.

The Short Version
Starved or pulsing flow on an Elite 3500 usually has a cheap cause. Check the inlet screen, the siphon hose and clamp, then the manifold and gun filters, before you look at the valves.
