Leak at fuel pump blue connector

[Smurfwarrior911]

Howdy all,
I've been having a small slow drip of a fuel leak from the fuel pump area so today I removed the cover and took a peek. What I found was the (facing toward the front of the car) Right side where the electric attachments are was wet. I dried it and watched fuel seep from the underneith the blue plastic cover underneith the electic connector, then drip... Please advise! The connection was not loose... new pump required??
Thanks in advance!

Bump! Need help!

I would definitely disconnect battery, unplug fuel pump fuse, and clamp line going to the pump (I use a small vice clamp). I would then inspect.

Others probably know better, but I would take the pump out, inspect all connections. Is the pump OEM? Is it aftermarket? If it's leaking I suspect one of the fittings isn't right.

Did you replace it recently?

Hope this gets things going.

It appears to be stock, and it is leaking not from a gas line fitting but from where the blue negative wire connects...just seems very strange to leak from there. Thanks for the response!

The internal seal between the fuel pump casing and the pump guts is starting to leak. When you replace the fuel pump you get to figure out :confused how to install a filter between the tank outlet and the pump inlet.

Thanks Ted, that makes sense then. I guess a new pump is in order

Order the short rubber hoses when you order the pump. U will be glad you did.

A year/type from the start would help.
A picture of the pump would help.
A search on how to order/change the pump will help.

Things to consider:
Many different pumps are available from Bosch and Pierburg either with internal or external check-valve.
Get a pump that can deliver the necessary system pressure: Around 5 bar, ~75 PSI for SC's.
The short hose from tank to pump inlet is a 12mm (Or 1/2") fuel line that can be bought by the foot. There is no filter between tank and pump; there is a screen on the bottom of the tank accessed by unscrewing the hex-plug.
I prefer to drain the tank instead of clamping the short hose.
Fire extinguisher close by.
Connect a 1/2" hose to the tank nipple, clamp the drain-hose securely, drain into a large container.
Most pumps have a 12mm banjo connection that is either just an adaptor (If the pump has an internal check-valve) or is an adaptor containing the check-valve.
You don't know until you dismantle.
Aside from the check-valve-issue, you'll need new copper seals for the banjo, and possibly a new rubber sleeve for the new pump if necessary.
Post a picture.

I replaced the fuel pump yesterday, pretty easy straightforward process using 911 Projects. Thanks Wayne! It Idles smoother and the fuel injection system seems to be operating better and has better drivability. Can't beat that!
