Mechanics taht use UV dye to find feul leaks
 

Hi,

I have a fuel leak, on a 95 Integra SE, but cannot find it. The car smells like fuel on cold days at startup.

Took it to 3 shops already, replaced o-rings on top and lower portions of fuel injectors. Also had fuel line checked, no leaks. Car is not dripping fuel either.

Anyway, instead of paying for another (visual) inspection fee, I was wondering if you guys know any mechanics that use a UV dye to find the source of the leak, or any DIY guys who have used this UV dye.

i know a good mechanic Pm because i dont want to advertise and get booted.

alot of cars do smell like fuel on cold days on start ups. cause your car idles higher when cold (cold start) it just dumps fuel in the engine. next time on start up take a wiff of the exhaust. only thing i can think of.

Look under your car and see if you see any wet spots on the ground, if there's a leek it will drip on the ground when stoped.

Have you taken the time to visually inspect all the fuel lines yourself?

3 Lines run from fuel tank (Fuel Feed, Fuel Return, Fuel Tank Vapour Purge)

These are hard lines, and run underneath the car, parallel with the brake lines from the rear calipers.

The fuel tank vapour purge line runs to the charcoal canister in the engine bay (located below the battery, and behind the throttle body)

The fuel feed runs to the bottom of the fuel filter (mounted on firewall next to battery)

A soft line runs from the top of the fuel filter to the fuel rail (mounted above injectors)

The fuel return line then runs from the fuel rail's Fuel Pressure Regulator (mounted on opposite end, or right side, of fuel rail) back underneath the car to the fuel tank.


If no leak is STILL found, then inspect the fuel tank/pump area. Remove your rear seats, and inspect the rubber gasket around the fuel pump, and also the fuel tank connections for all 3 lines.
