NEW Integrated pump sender combo!

[Citizen]

So I finally got this thing installed.

Were you able to change the fuel filter without any problems? Not trying to be nosey, just that I had some problems with mine.

The only problem I ran into was that it's kind of a pain in the ass to get at the nut for the clamp that holds the filter in place. Other than that, no. No problems.

I'll be helping a friend install one of these shortly. I'm interested to see how it all works out.

I gave up on that nightmare and just removed the entire clamp assembly, uninstalled the old filter, pre-installed the new filter to it, and then re-mounted it.

That's how we do it, and it seemed so obvious that I didn't realize people were changing the filter without taking the clamp off the frame.

What are some reasons I would start smelling gas after driving for an extended (1+ hour) drive after replacing the old pump with this new one?

Check the other fittings, i.e. the rollover valve. I've seen the factory install of the upper cover crush the vent hose, which will cause the tank to pressurize. The pressure has to go somewhere so it either burps out the fill cap, sender, etc wherever it can get out. Make sure someone has not capped off the hose to the carbon cannister - same problem. The delay you see implies to me that the tank is pressurizing or trying to.

This is an interesting theory. Immediately after the initial installation of the pump I went out for a fairly long test run (45 minutes or so) and I don't recall smelling gas. If I did, it was slight and I'd probably assumed it to be the result of having been screwing around the tank for half a day.

The interesting part is, I went for said drive with the fuel pump access cover not installed. (I assume this is what you were referring to by "upper cover"?)

Also, what's the best way to get at the fittings for the rollover valve? I have to wonder if any of these other things are the case since I didn't have this problem until after I replaced the fuel pump.

I do think it's a pressure issue of some kind, because everything you said here makes sense. When I got home and checked the fill cap, I pulled it off and the fill tube "coughed" at me, expelling some vapor. I guess it's just a matter of figuring out where/why the system is building pressure.

The upper cover is the odd-shaped cover that covers the filler tube and rollover valve. There is a small hose in there that goes to the rollover valve and sometimes it gets positioned so that the cover crushes it.

Ah! Now I know exactly what you're talking about. Part number 106002 - the cover that takes some work to figure out how to properly fit its gasket.

But yeah, that also makes sense since I didn't have that cover completely secured either when I took my test drive. After I got home I wanted to put everything back together properly and those covers were both missing nearly ALL of the screws when I first got the car, so I took this opportunity to secure it correctly with a screw in every hole - on both the pump access panel as well as the upper cover. (By the way, what's the part number for the correct screws to use on these panels?)

I pulled it off and it looked like the hoses MAY have been in a somewhat-kinked position, but they were definitely in a position where things were tight. I'm going to play around with their orientation and hopefully that'll do the trick.

Once again, thank you Dave. Let's hope this works.
