So I did t pull the lift pump. I suspect it's fine. I added 3 gallons of fuel to the rank since one gallon wasn't enough to really cover the bottom and I think it was sucking air so three it is. I spent 20 minutes trying to prime the system.

Spin on is 100% full of fuel.
clear filter has no air in it
All fuel lines are tightened down
Injector soft lines are new
Fuel supply rubber hose in engine compartment is new

While trying to prime I put a light on the clear line coming off of the lift pump and I can see fuel moving up but it gets to maybe 3/4 and won't go further or any variation of that but not more than 3/4 of the way up the line.

What gives?

Do I need to put more fuel in the tank so there is adequate pressure behind the lift pump? Could I have a leak somewhere?

That is all

Have you tried with a small can of fuel in the engine bay? Might be worth a try to see if you can get it running that way then worry about the tank and lines.

I tried that and couldn't prime the system off of the tank of fuel I had in the engine compartment

John, as with any decision, there are variables. I am not limiting myself to specific areas, especially if the other venerable out number the others. I was looking in the Payson area, but with my pittance can't afford what is left, especially with the club fees. So expanded out and see a lot of options.

If I had to guess, your land is more near Maricopa, Sun City, or Apache Junction than Phoenix and have the diurnal temperature swing that I meant by avoiding urban heat island. Also, that large of a plot aren't existent in the city.

Is it possible a seal dried out in the pump?

Are you getting fuel from the hard lines?

Hope this helps...

Double post

No fuel to the hard lines because I cannot get fuel to even prime the injection pump.

I was taught to eliminate to a point so as to find the solution. So is there a way to tell if fuel is getting and through the pump?

You could maybe try putting a little compressed air on the return hard line. This will force fuel from the tank to the inlet of the lift pump if you still can't get it to prime then I would think there's something up with the lift pump.

Having a Helper on standby to open the fuel tank cap to relive pressure is good.

I need to clean the tank vent valve just so. Everything related to the system has been gone over. I'm sure it's something stupid causing it to not prime.

Oh and did you remove the lift pump and see if you could push the piston in by hand? I had two lift pumps seize from sitting and the piston couldn't be pushed in...

This should be the next step.

Alright I'll remove it and see what's up. I almost removed it the other day but decided to try pumping from the tank. Looks like it just slides off the pump.

It does, just remove the three nuts, and it will just slides off, you will lose some oil though.....
