About to change post '80 style fuel filter. Haven't done one for years. WSM says to disconnect and "catch escaping fuel". A whole tank full? On other cars it is necessary to pinch a rubber line to contain the fuel. No such obvious place on my GT. There is a rubber line from the tank to pump but it is very stiff and marked 100 psi. I don't want to fool with it for fear of creating a problem. Can I simply remove the tube fittings from the filter and only need to catch the contents of the filter? Help please.

I have ran my tanks as empty as possible before changing the filter and still get a good amount of fuel out. If you don't pinch the line it will continue to drain.

Nope it will drain the tank...... you need to pinch the hose it should be flexible enough not to damage it. And it is a low prsssure application for the hose highly doubt it is 100 PSI hose.

Jim Chambers

Hose seems fairly brittle and is stamped "100 psi".

X3 - alligator-nosed vice grips and two flat pieces of wood (construction shims or better, popsicle sticks). The line doesn't have to be squashed flat, just pinched enough to seal... easy once you look at it.

<saw your reply> if the rubber parts look brittle you may be stuck replacing. The plus side is that since you will need to drain the tank, you can change all of the rubber lines associated with the pump and filter.

Jim,

Run it out until you only have a tiny bit left. Then plan on catching that leftover bit in the gas can you use for the lawnmower or the bass boat. You'll need some to put back in to get to the gas station anyway. Then plan on replacing all the rubber back there. If it 'seems failrly brittle' it's time to replace it anyway. Good chance to do it all at once.

I now keep a bunch of different sized rubber plugs and boots for this type of thing. Quick action and a bucket limits losses.

I just pop it off the pump and put a bolt in the end.....

James Bailey

Yes if you do not mind putting your thumb over the hose to stop the fuel flow until you get the bolt ready to go in place ......

This from a 911 owner, someone who derives a perverse pleasure from having fuel run down the arm into the pits/shirt when pulling fuel hoses.

My limited experience using bolts as fuel hose plugs taught me how fuel will find its way through the bolt threads. I've settled on a pencil as the weapon of choice for plugging 8mm fuel hose.

My fuel pressure gauge test plumbing lets me hook up a length of hose to the fuel rail port, hose runs to a gas can. Jumper the FP relay and the pump will do all the work for you. No muss, no fuss, no armpits-o-fire.

I used a fuel line hose brass coupler and a valve, pull off the hose connect to coupler if you want to drain your fuel, this way you can control it. If you squish an old hose plan on replacing it how is your tank filter?

NOTE tie a rag around each wrist so the fuel wont run down your arm and give you a new kind of BO wear blue gloves as well.
replace the tank to pump hose

Is it difficult to r and r the tank screen? Seems like it should be done while replacing the hose.

If the tank filter hasnt been overtightened, shouldnt be hard, but ...Mine spun the tank insert, and I had to seal it with PC11. This worked for several years until I replaced the tank. If you also have the in-tank pump, you SHOULD check its hose to outlet, and probably replace - do a search for this one. My local wrench's advice on refitting the filter was barely more than hand tight , and only if it leaks at that.

The tank "filter" is a mesh screen it should not need changing and you do risk spinning the threaded ring that is molded into the tank........see post above .
