I have a 1991 940 GLE. I've never check or replaced the flame trap, so I bought one and went to replace it today.

When I pulled off the plastic housing (with the 2 hose connections), then the short hose the housing plugs into, I expected to see the old flame trap in the flange (that the short hose was connect to), but there was no flame trap there. What I could see in the flange was what looked like a flame trap, but with bigger holes, and it was machined into that flange.

My question is, does the 940 GLE have a flame trap and it was never installed, or was that component in the flange (which couldn't be removed by the way) the flame trap?

FYI, I bought the flame trap out of the IPD catalog, and it was listed under the 900 series, so I assumed that it was also for the 940 GLE. Was I wrong?

Thanks

I have a Hayes manual,but it doesn't cover the GLE (16 valve) engine, and it doesn't cover flame traps anyway.

Looking at the IPD catalog, it shows the flame trap (in pre 87 Volvos) installed in the plastic housing where the two hoses connect, and I double checked mine, and there wasn't one there. Now I'm not sure that if mine does require a trap, does it go in the plastic housing, or the flange. I suppose I can call IPD to clairfy this.

I am not sure what you are describing, but, unless your car is a turbo, it should have a flame trap. Sounds like someone has maybe just removed the original and not replaced it. You probably should get a manual and check photos to be sure. Otherwise, just clean everything up with WD-40 (including hoses), stick the flame trap you bought into the flange, and put everything back together.
