What This Thing Actually Is
It's a separator clamp, not a full hose clamp — its job is to hold two 3/8" lines a fixed distance apart so they don't chafe against each other, the frame, or a bracket. Cheap part, easy to lose track of, but if it's missing or cracked you'll know because you'll have a wear spot rubbed into a coolant or fuel line eventually.
These show up in engine bays and along frame rails on pretty much any heavy-duty diesel setup running dual 3/8" lines side by side — cooling system runs, sometimes fuel supply/return pairs. Not model-specific by nature, since it's a generic spacer, but the OEM number 11548 got assigned by whoever specs it for a particular routing point.
Since it's a small stamped or molded piece, the physical spec that matters is the 3/8" line ID/OD it's clamping — get that wrong and it'll either not seat or it'll squeeze the line.
Why All These Numbers Cross
11548, 10QE125, 94056, 34020, 022024, and the aftermarket-branded M11548 and TA34020 all reference the same physical part — a 3/8" separator clamp with matching hole spacing and jaw width. Different manufacturers stamp their own part number on the same tooling, and OEs will often re-badge a supplier's part under their own catalog number.
The thing to actually check isn't the number matching on paper — it's whether the clamp gap and hole spacing match your old part. Lay the new one next to what came off the truck. If the jaw opening doesn't match your 3/8" line snugly, or the mounting hole doesn't line up with the bracket, it's not the right one, no matter what the box says.
Since this is used across multiple platforms and there isn't one single 'this only fits X truck' rule, pull your old clamp or check the number cast into the bracket/hose routing diagram in your service manual, and confirm against your VIN before you order in bulk.
Ordering From Us
We stock 11548 and the common aftermarket equivalents at the Tacoma counter — it's a $4 part, so we're not going to upsell you on it, but we will make sure you're walking out with the right jaw width for your line size.
Local shops can grab it same-day, will-call or we'll run it out. Anyone outside the Tacoma area, we ship nationwide and it usually beats the truck getting back on the road.
Standard 6+ month warranty applies if it's defective out of the bag — but on a piece this simple, the main failure mode is buying the wrong size, so double check before it goes in the cart.

Frequently asked questions
Does 11548 fit my Freightliner Cascadia?
Probably, if it's clamping a 3/8" hose pair in a similar spot, but confirm by pulling the old clamp or checking the number against your VIN-specific parts list — this separator isn't unique to one chassis.
Is TA34020 the same as the OEM 11548?
Same physical spacer clamp, different manufacturer stamp. Cross-references fine on spec, but check the jaw width against your old part before installing, since low-cost stampings can vary slightly.
Can I use this on fuel lines instead of coolant lines?
Yes, as long as it's separating two 3/8" lines and the clamp material is rated for the heat/chemical exposure in that location — check your old part's material if you're not sure it's fuel-rated.
