Mike:
Just a question: Did you tell the hardware store they were for fuel?
If they supplied EPDM type o-rings, the fuel will break down the material, and you will have leaks again.
I work for Bosch Rexroth (yes, sort of the same Bosch that makes parts our cars don't like, only I work for the hydraulics division) and I've seen first hand what catastrophies the wrong type of o-ring can cause.

Viton or Buna will be fine. You might want to call the hardware store and make sure they did NOT supply EPDM.

Sincerely,
"Lord of the O-Rings",

Hello! BillBoost37

I removed the O-Rings with a pick from the female side,the clip stayed on the male or tubing.
There were 2 o-rings, a Yellow one in the innermost part of the female part, and a Orange o-ring that was further to the outside,they were Hell to get in and it took three attempts but I Got It! :lol:

For future info the O-rings were RA#12 at the hardware store!

Thanks Again!

I'll stress something that has been mentioned here already...

MAKE SURE THE O-RINGS ARE RATED FOR FUEL. This is a SERIOUS FIRE HAZARD potential.

Hi! guys

I did get O-rings that are rated for fuel lines!
I live in the Country and the Hardware Store is also a Hugh old Style Auto Parts, Like we all used to have before the Discount Auto Zones and Hi-Low-OReilly's.
The guys their actually know what they're talking about and took the time to Match up the O-rings for me!
Oh! That # was BA 12 not RA, I think :? . Oh Well, it's fixed. ;)


Thank for all the info and Help!

Like mentioned and you've confirmed.. We can't stress enough to all that might read this thread about ensuring the o-rings used in the fuel lines are made for fuel.

Most o-rings would be slowly eaten away by the gasoline and then a pressure leak would occur, spraying fuel all over a hot engine and exhaust.

In this case, fuel o-rings were gotten at the Auto/Hardware store.

Glad to hear you were able to get it fixed up and back on the road.
