Re: [DML] Re: Fuel Pump Noise (Moving the Pump)

["Tom" <tomciodmc@xxxxxxxxxxxxxx>]

Hi all

I'm not sure if I can agree completely with this. I mean, if you mount the 
pump 'just anywhere' it might take a long time for it to prime if it starts 
dry. Long enough to ruin the pump. So, I would keep it close to the tank. 
One thing is for sure - the pump DOES NOT need to be mounted inside the 
tank. I have seen identical pumps mounted on top of the fuel tank that 
lasted for many many miles (on different cars) without any pump inside the 
tank. A good example is a Mitsubishi Starion. Where is uses the same pump as 
the DeLorean. The pump is clamped to the top of the gas tank. It's connected 
to a metal pick up line with a short piece of rubber fuel line. The metal 
line goes all the way down inside the tank and has a pickup screen at the 
end. And the tank itself is deeper than our tank. It's about 28cm deep (11 
inches). The pump in this car lasted for the life of the car - the engine 
blew at over 200k miles. Even when I took it out it was still nice and quiet 
and it went in my friends car. So, I definitely move the pump outside the 
tank and make the pickup and return hoses out of metal. As a matter of fact 
I'm working on a setup like this for my car... and if it works good I will 
offer it to other DeLorean owners. I want to forget about the pump and the 
noise once and for all.
