need some fuel system advice 700 1986


Open the gas cap and just put your ear to the hole. Do you hear a whine or buzzing sound from the tank? It isn't hard to hear, so if you don't "think" you hear it then you don't (it's obvious).

If the in tank pump is shot I suggest you do the replacement yourself. It's an easy job, and the amount you mention is ludicrous. Get the parts from the following site:

http://www.importeccatalog.com

Just enter your make, model, and year and than go to the fuel category. You will want to purchase an in-tank pump and a new sock that sits on the end of teh pump and bottom of the tank. The socks get dirty over time, and you might as well replace your old one now.

You might also want to buy a replacment hose for teh sender arm. One known failoure is that a hole can form in the hose from the sender arm (metal pipe) to teh in-tank pump. When the gas level drops below the hole air enters the fuel line and tsalls the vehicle. If you are experiencing no start or stalls at about 1/3 or less of a tank this might be the reason.

The parts you should buy are listed below:

Fuel Screen: in-tank (pre-pump sock), $6.37
Fuel Pre-pump: in-tank, $33.93
Fuel Hose: right one for your vehicle, $4.77
(they list different ones for wagon and sedan, but I'm not aware of a difference in design of the senders.)

YOu should make sure this is the problem before you go to teh trouble of replacing it though.

good luck,
rt
