I filled the housing up with fuel before putting the top back in. hooked up a preassure guage, but get no preassure . and the tower is almost empty of fuel. Is that small housing that the fuel line comes into below the lift pump supposed to be a check valve? it only had a spring and a lineup button inside to keep the spring straight. Is there another part that is missing? I don't know how it could be a checkvalve the way it is. any ideas?

Hi,
It sounds as though you've found your problem.
There should be a top hat shaped plunger with a rubber looking seat on it at the end of the spring. It is the fuel pressure releif valve without which you cannot make fuel pressure so the engine will not start.
In service we found we had to replace the plunger and spring from time to time if fuel pressure dropped off, most Cats are simmilar.
You should have no problem getting replacements and I would use a proper Cat guage if possible.
A kit is available to change the cotton reel /sock type filters to a paper element if you wish, I have changed a couple rcently.
