Good evening everyone, I recently tore the engine of my 2002 Blazer apart to replace the leaking lower intake manifold gaskets. I've gotten it mostly put back together now but I've run into a bit of a snag.

When I reconnected the fuel lines at the rear of the engine bay I wasn't sure if there were supposed to be any o-rings in the lines...I didn't see any in there when I took it apart and so I put it back together without any. When I turned the key (to get the fuel pump to prime the lines) I noticed fuel was indeed leaking out of the connection...so my question is:

Do the fuel lines at the rear of the engine bay require o-rings and if so does anyone know what size(s)?

These lines (I don't have a camera sorry.)

Any help is greatly appreciated, thanks for your time.

 

Yes, I believe there are supposed to be o-rings back there. I do not know the size though.

I had a similar problem when I replaced the spider in my old Bravada. The connection on the supply line ended up getting cross threaded slightly and didn't tighten down properly. Maybe check that out as well.

 

You can get them at the dealership. I think I paid around 3 bucks for both of them.

 

Wow! Thanks for the quick responses I really appreciate it. I've been battling with this thing for weeks now trying to get it all put back together (Been without my poor Whale Wagon for 6 months!). I have a couple of o-ring kits around. Hopefully they'll have something that fits.

 

The orings came with my intake gaskets they are real small one is a little smaller than the other. you may want to take both bolts that hold the lines to the intake off It is so tight back there with the distributor in, I wish you luck

 

Personally, I wouldn't use standard rubber orings. These are specific and
made of Viton, a fuel resistant material.
