[DML] Re: Coil in Fuel Line to Prevent Collapse?



The article is in the Technical Library on the DMCNews website with 
the full instructions.

I wrote it with the help of input from others. But I can tell you 
now that in the long term it isn't the best solution. But there is a 
better one.

The problem with the spring is that while it will snake around 
through the hose, it will also begin to try and straighten that hose 
out. And with the hose material being so soft, it WILL eventually 
tear the hose at the 90° angle in the hose, right where it connects 
to the bottom of the fuel pump. Sure, you may not have the spring 
sitting up inside of that bend, but the spring will push back 
between the baffle and the pump, pinching that bend until it finally 
tears. I don't know of it's the ethanol or MTBE additives (since 
banned out west here because of California) that dissolve the rubber 
components of the fuel tank, but it ate both my pick-up hose, boot, 
and eventually cap around the fuel pump.

There is a better solution however than either the spring, or even 
the OEM setup.

Using John Hervey's kit is ideal. But if you plan on doing any hard 
cornering, you'll realize that you're going to need a solid bottom 
on the new fuel baffle. I heard that John sells them in another 
post, but a better solution is at the grocery store: A large Tuna 
can.

Remove label, wash the can thouroughly, drill a hole on the bottom 
of the can to mount it to the bolt inside of the fuel tank, and then 
drill small holes around the bottom sides of the can (use your OEM 
baffle as a template). That's all you've got to do to make your 
custom baffle.

Just mount the new baffle inside of the tank, and drop in the new 
fuel pump with the hose and pickup screen right on the end of it, 
and be done with it all. Just in case you ever need to replace that 
fuel pump again (by getting rid of the collapsing hose you'll 
greatly increase it's lifespan), you just have to drop the new pump 
in, and not worry about twisting or kinking any pick-up hoses ever 
again. In fact, you could easily change out a new fuel pump in low-
light conditions.

And just incase you're put-off by the idea of using a tuna can 
inside your car, just rember that Ford uses coffee and juice cans in 
their vacuum systems on their vehicles for years (look under your 
hood if you don't believe me).

p.s. A big thanks to whomever came up with the idea of the Tuna can-
baffle. I read this on a DeLorean message board a couple of years 
back, but I cannot remember whom to give credit to for this idea.
