Those valves are designed specifically for each engine as far as spring pressure and flow rate.
Yes, that is also my understanding. Just got the valve this morning. They gave me the non-gold plated one so it was only $14. The first thing I noticed is while the old and new valve were identical on the outside, the new one had a blue plastic piece inside looking through the grommet end the old one had nothing. The new one had resistance blowing thru one end while the old one does not. After installation, my engine idles at 600 instead of 750 so I guess I fixed a vacuum leak with the new PCV. Took it to PROcare for an inspection but they are full up on inspections today. Maybe another time. Back to the gas filler tube issue now.....
Have you run any seafoam/fuel injection cleaner/carbon buildup killer?
I have used one can of Seafom and one bottle of Lucas. Im thinking that would be enough. Just checked out my filler and vent tube. No apparent obstructions so meh, I might just have to live with the gas filling hiccups. I broke the clamp that holds the main filler tube to the tank hose. I want to get a new clamp before I fill up. Looks like I will be over 700 miles.
Did some checking into fuel tank size. This is the only reference that I could find.
Notice in 92, the CX/VX had 11.9 gal tanks like the other HB's but starting in 93 they went down to 10.0. I am hoping that the 11.9 is a typo cause 10 gals would make my 700 miles look better. I will find out soon enough i guess.
