I'm fairly certain my 94 Ram has either a bad fuel filter and/or fuel
pump, and the gas gauge has been broken for over a year.
So I need to drain the gas to lower the tank, but the engine won't
run, which means the the fuel pump won't run.
I'm pretty sure that the gas fill spout has anti-siphon in it to block
Any suggestions ?
That sucker is HEAVY, especially with camper shell and bed liner; also
would need to disconnect a few wires.
I want to get the tank out anyway - what's a good way to clean out a
gas tank, remove and rust and gunk??
Use a scrap of plywood and a floor jack. You will have to disconnect the
fill hose and there are some hoses swaged on at the top of the tank. You
have to lower the tank a little and get the hoses off. There is not a lot of
play. Be sure you can support the tank while you cut the swages off the
hoses. On my truck the hose from the fuel pump to the round plastic plate in
the top of the tank broke off. The pump was working but no fuel came out.
Autozone had the OEM pump.
I had heard that the fuel filter is "part of" the pump module, but
I've seen internet auto parts sites selling the filter by itself (for
Just want to double check: is filter replaceable once I get the module
out? I'm going to order a filter no matter what, but I'm hoping to get
lucky and not actually need a ($200) fuel pump.
PS what is a "swage" ? the short rubber hose pieces used to join the
fuel line to the tank???
You need to check but I'm almost sure the filter is in the tank. The hoses
have Aluminum sleeves on the ends that are swaged. It's like a crimp in an
electrical terminal. I cut mine with a flexible shaft cutoff tool to keep
the motor away from any fuel fumes.
On some versions of the pump assembly, the filter is replaceable but it is
still in the tank with the pump.
Exactly how long do you think this pump is going to last? It would really
suck to take the tank down, spend the time rebuilding the pump assembly,
reinstall it back into the tank and then have the damn thing fail again a
year later because the old pump finally gave out.
If at first you don't succeed, you're not cut out for skydiving
A motorcycle jack works great for dropping the tank.
You can undo the fill tube and get your tube into the tank from there. That's
how I did mine with 25 gallons in it.
Fuel pumps usually don't go bad when you have a near empty tank. Don't ask me
how they know!
That's a good idea about undoing the fill tube to siphon the tank, and
obvious (once someone said it!).
re fuel pump and empty tank : apparently the gasoline keeps the fuel
pump cool, when tank is almsot empty, pump can overheat (from what I've
read on the web).
I heard that because of the heat generated by modern fuel
pumps (with the higher pressures and constant runs), that
frequently running your gas down towards empty could end
up shortening the life of the pump.
The gas itself helps cool the pump so running the tank down
toward empty frequently, means the pump runs hotter for
longer periods of time.
I know I typically run my tank down low and did end up
replacing my fuel pump at about 90K miles, which I thought
was a tad on the premature side.
