I'm hoping a friend has a NIB walbro to let go and I'll find out shortly after. You think I can just slide the bed back far enough to get the job done without dropping it (the bed)?

 

Dropping the tank is not bad at all if it is mostly empty. With it 3/4 full it really sucks

 

i installed a walbro not to long ago, and have been very happy with it. I just let the key turn on for a few when cold and mine fires right up. Also, when i done the fuel pump swap, i cut a trap door through the bed right above the pump. Ended up working out really well, makes for a very easy fix or fuel pump swap.

I also, have a rubber bed matt in the back that covers up the trap door. You cant even tell i made one.

 

Yes you can, but youll def need a helper cuz its kinda heavy for one guy lol.

You prob have to lift it up over the rear tires IIRC.

 

Dropping the tank is a pain the *** even when close to empty, id rather unbolt the bed.

 

I would look into converting to a return style. I made my 05 a return style. Look into a FPR from Magnuson that mounts on the rail. You want to have your regulator as close to the rail as you can, and preferably after, but the Magnuson will work fine. The cheapest fix might be the inline check valve. Is the problem still there if you cycle the key a couple times before cranking it?

 

I really don't want to do any more than I must.

Yes, even if I Key ON and Off a few times, It will crank, sputter and sometimes die. The next key on it fires right up. It's only after sitting a long time, say 5 hours or more that it behaves like this. Did I mention it's been this way for 2 years or more?

Key on I can hear the pump pressurize, watch the pressure on my gauge go to 58. Leaving key on without cranking I can see a steady slow drop of pressure for as long as I allow it.

Maybe Tim is on the right track with an inline check valve, get 'er done Tim and report!

 

Bill, this is telling me that you either have a leaky injector, or it is bleeding back into the tank(check valve). Have you tried injector cleaner or a Motorvac service already?

 

I thought it might be an injector except for the fact that it stumbles more than missing on a single cylinder, fuel deprived if that makes sense. I'm almost positive it's the check valve or lack thereof and others with the same pump are experienceing similar issues with them.

 

With your TVS having the front inlet, it would be very easy to pull the injectors(leave them attached to the rails) and check them. Key it up and look for fuel at the nozzles. Easier than pulling the fuel pump. Plus, if you do this, and they stay dry, then you absolutely know where your problem is. No guesswork.
