Fuel problems persist

So I posted about my fuel filter change outs and now my prime pump is leaking so I have one on order.here is my problem: when I hit the ignition, I hear a pump clicking. Is this the fuel transfer pump? I read that the water seperator gets fuel thru vacuum in the lines. Am I understanding that correctly because I removed the filter again and it is empty after i initially filled it at install.this filter should always be full and daring any water from bottom as necessary. Am I missing something here???

It would seem you are not getting fuel from the tank to the prime pump.


Have you drained some of the fuel from the tank to see how it looks? The filters really look nasty and if they have rusted, then there was water in the fuel. Water in the fuel usually come from the tank.

Fuel filters

Yes I drained 25 gallons of fuel from tank. Put 18 gallons of fresh fuel in and star tron fuel treatment. Once I figure out what the heck is going on with this crap, I can take for a spin and start burning some fuel.

It's possible the two fuels are "summer blend" and "winter blend" (they will appear different), when was the 2 fuels purchased? Even in Florida, during winter months most fuels will be winter blended, mostly for truckers who may end up in very cold northern states before fueling again.

take a shop rag and a blow gun to the tank fill port and add some pressure to the tank while having somebody pump the primer. when it gets hard to pump close and lock the primer pump [or it will suck air]. keep the shop rag and air on the tank and try starting it

my fe does not use a lift [electric ] pump. race your fuel lines and see if you have one. if so disconnect the feed hose at the primary and see if your lift pump is plugged

I agree its not the main issue. It seems you had a problem from the start and got some good advise in your "Fuel filters changeout issue" thread. If the junk on top of the fuel separator is any indication of what was in your tank, it a good bet that more of that has clogged or partially clogged the fuel line or fuel pick-up. If the primer pump is leaking it could also be causing a vacuum leak. Just my thoughts. Sorry you are having this issue.

Thanks guys for the valued input. I drained 25 gallons since I the bus was losing power several times driving it home. Furst time driving a bus 125 miles and pulling onto highway shoulder 4 times was very stressful but I made. My old nasty water seperator was bone dry which prompted me to change filters immediately and drain some fuel just because of the unknown.so I am changing out the prime pump handle and will see what happens.the empty seperator is very concerning.

make sure the primer is closed and locked before starting as they will suck air if not
