I got off from work early today and thought I would finish up my alluminum sunvisor mounts, I was wrong. I picked up an extra decel valve and decided to open it up. I plugged mine because It was all jacked up. I know most dont use their decel valve anymore, but thought if nobody had opened one up and posted it here before, this might help the ones that still have them.

That is a decel valve, the FPR is similar. The 1.8 FPR has three fittings on it (fuel in, fuel out, manifold vacuum) and is not adjustable; the 1.7 and 2.0 FPR has two fittings (fuel in, fuel out) and is adjustable. The adjustment on the DV looks like the one on the FPR, but the fitting is much bigger on the FPR.
The 1.8s (except possibly some very early ones) had the flat disk skaped DV. The one shown here is a 1.7 or 2.0 one. (Or maybe that early 1.8.) The DV got hard to find a while back, so it is possible that the 1.8 one was retrofitted to other systems. I think the 1.8 version was still available for a good while longer because of its use in the Bus engines. --DD |
