hi i am looking at buying an '85 gsl-se that needs a new fuel pump any body have a used fuel pump for it that i could buy( the new ones cost around $380.00)also i was looking under the car near the fuel tank and there is a hose hanging down that ,since the owner won't let me jack it up without buying it first, i can't find where the hose goes to i think it goes to the the old fuel pump but i don't know. please help.

 

What's that hose look like, and where is it, exactly?

If the end of it is neatly cut, but at a bit of an angle, there's a good chance that it could be one of the drain hoses for the water channels in the trunk. Those are usually a brownish-yellow, but I think they started life as clear PVC tubing. If it's part of the fuel system, it'll be a black hose, but the end should be cut flat.

 

SE's have a few intricacies in the fuel system near the tank, one of which is a very large (comparatively), and metal fuel filter with metal line fittings. The other is the Rollover Cut-Off which shuts off fuel flow if the car rolls. Out of this is a vent that goes into a small metal 'pot' that is mounted to the frame that is supposed to keep road grime and stuff from getting into the valve and causing problems. The rubber hose that goes into the 'pot' has the end cut at an angle to prevent it sealing down, and it's not really critical to fuel flow or function.

The Fuel Pump is located under a protective metal plate and requires removal of the plate to get to the pump. There are plenty of aftermarket pumps for cheaper than a Mazda Factory OEM replacement, but be sure it's for Fuel Injection systems. These run at much higher pressures - but you probably already knew that.

While you're doing the fuel pump, you might want to get the fuel filter from Mazdatrix or VB just to do it all at once. Also, buy about 10 linear feet of FUEL INJECTION HOSE (specificall for fuel injection!) at your local parts house to redo all of the hookup lines and pressure lines - this prevents leaks and your hoses are probably due for a change after 20 years. HTH,

 

Loose Hoes!!! didn't someone tell you this was a family site!!

 

it looks likes a farely large black hose that has a been cut flat. i plan on changing the fuel filter but the fuel lines look to be in very good condition they show no signs if dry rot or anything common with old hose lines

 

Might want to check the car VERY carefully if the owner won't even let you jack up the car to have a look, just my 0.02 cents.

 

its at a dealership and it is really his mech guy that won't let me jack it up( he's an a**).any body know if the fuel pump is 258pph@15 psi or if it is 480pph@15psi
