Do you leave the out-flow side hard fuel line attached to the lift pump(removing it from the filter housing end) when taking out the old pump?

Yeah that is the same as mine. I can not see where the fuel line comes off the pump as it sits on the engine (going to the filter housing) and it seems like it might be easier to remove the pump with the line still attached at that end.

I guess you are saying that disconnecting it at the pump itself shouldn't be much trouble?

That's where I'd take it off. Otherwise, unless you are replacing both the line and the pump you will just have double the number of fittings to screw off and back on....

Yeah I would have to agree with you. And the shape of that line makes me think it might get hung up trying to get it out still attached to the pump.

I guess I just got to get my head down in there a little further.

thx for the reply

If you change your fuel filter and the engine and filter won't prime your probably looking at a bad lift pump.

It makes it easier to change the pump if you get some longer bolts of the same size. I've changed several without using them but it is a pain in the butt.
