2001 Mazda B3000 Fuel Pump Connectors

[P3x]

Had a fuel leak running down the frame by the fuel pump. Found a tube - the largest (OD Approx.575.0”) had a bend with a pin hole leak. Replaced the pump several years ago with an Airtex. Purchased the Dorman Fitting Tool and replaced several fuel lines/connectors that looked rough while I had the bed removed.

The leaking line routes from the largest fitting/port on the Fuel Pump (Approx. 630.0" OD) to a Y Connector on the left frame rail. From the Y, it looks like one line runs Aft to the Evap Module(?) with the other running forward to the Fuel Filter.

I've been searching online, local Parts Stores, etc. trying to get a PN for a replacement Quick Disconnect fitting and a section of replacement tubing with no luck. The only lines connectors referenced for B3000 and Rangers are 5/16 and 3/8. Contacted Dorman to see if they had any info available and the Rep said they do not.

The current Quick Disconnect Fitting does not look bad after removing the damaged portion of nylon line from it. Am thinking to use rubber Fuel hose to connect to the pump and a barbed fitting to connect to the Y . Would like to keep the truck as original as possible and figured I'd post to ask a knowledgeable person what the deal is with this line before modifying it.

Would appreciate if one familiar with this line can educate me on this Fuel Line and shed some

that is not a liquid fuel line. it's vapor recovery & emissions line.

Is there any fuel in this line when you turn the key to On and the pump starts up? With the leak spraying fuel it's difficult to determine which line is the problem when you're a one man band.
Since the pump activates when the key is placed in the On position, I positioned the battery by the rear cab and used a set of jumper cables so I could see where the leak was coming from. when the the pump activated. Look like it was coming from this line as it had a kink/bend and had a pin hole.

But, that's good news since I have the Dorman tool and 5/16 and 3/8 repair kits. Just need to determine which line is the offender.

You got to love working on older vehicles. I washed the truck and prepped the bed to paint it with POR Bedliner. The carpet always bugged me as the previous owner must have been a smoker/toker since it had numerous burn holes. So I ordered a replacement and gutted the interior. Then I see it pissing fuel.

Thanks for the replies.

Love this site!

uel sprayingThere's no fuel running Well, it will be easy to fixSo much for me figuring it was the main fuel supply line!

That big line that goes to the Evap canister and up towards the front should only have vapor in it. It bypasses the fuel filter and goes up to the front of the engine for vapor stuff. There’s usually a metal line along sections of the frame for it. In PA, that metal line likes to rot out and create an Evap leak. I’ve been replacing mine with fuel rated rubber line and aluminum tubing. It’s low pressure so no worries there. The other two lines go to the fuel filter, one is a pressure and one is a return, and those are 5/16” and 3/8” fittings. I just replaced both of those on my green 00 Ranger recently and went to -6AN line and fittings because I had that stuff on hand.
