Fuel Pump Fitting (For Walbro Pumps)
Drop a Walbro pump into a modern fuel system, and you meet the same snag every time: the pump's barbed ports were made for rubber hose and worm clamps, not the high-pressure, ethanol-ready plumbing a serious build runs. Black Market Parts solves that right at the source. These billet fuel pump fittings thread onto the pump and give you a clean, sealed interface for AN or quick-connect lines, turning the weakest link in the setup into one of the strongest.
Why the Stock Connection Falls Short
A hose clamp on a slick barb is acceptable at low pressure and poor at high. It can weep, it backs off through heat cycles, and it looks out of place beside braided lines. A purpose-made for Walbro fuel pump fitting replaces that clamp-and-hope joint with a threaded, O-ring-sealed connection built for the pressure a 450-class pump actually generates, so nothing loosens when the car gets hot and hard-driven.
One Piece, a Cleaner System
The whole point of these fuel pump adapter fittings is to convert the pump's native port into the standard your system already speaks. Rather than stacking reducers or trimming lengths of hose, you thread the piece on once and land straight into your chosen line. Fewer joints mean fewer leak paths, less clutter around the pump, and a far tidier engine bay or tank area. It also makes future service simpler, since there is one solid interface to disconnect instead of a hose that has bonded itself to a barb over the years.
Keeping the Factory-Style Lines
For cars that keep OEM-style plumbing, the fuel pump quick connect fittings let a Walbro pump plug into a factory push-lock line with no cutting or crimping. Push it home, feel it lock, and the sealed joint is ready to pressure-test. That makes a pump upgrade far less daunting for someone tackling their first swap in the driveway.
Materials and Fitment
Machined from billet aluminum and anodized, the piece is meant to resist ethanol and under-bonnet heat, while an internal O-ring carries the seal. It is designed specifically for Walbro inline pumps, so Walbro fuel pump fittings in this range are cut to match the pump's port rather than forced on with shims or thread tape. That direct fit is what keeps the joint honest over the long run.
What You Get
- The BMP billet piece, ready to thread onto the Walbro pump
- An O-ring seal for a clamp-free, leak-free joint
- A direct interface for your AN or quick-connect line
Installation
The job is quick and needs no fabrication. Relieve the fuel pressure, remove the old clamp and hose, and thread the piece onto the pump port by hand until the O-ring begins to seat. Snug it gently, connect your chosen line, and pressure-test the system before the first start. With no crimping and no special tooling, most owners have it done in minutes and gain a connection they can trust every time the pump comes on.
