Fuel Pump R&R

I have a 87 turbocoupe, need to replace the fuel pump and was looking for any tips on the process. I will be using the walbro 190 lph pump, comes with install kit with O ring, clips, sock, hose and wiring adapter.

I did replace a fuel pump in my 96 Impala a month or so ago, but that pump was bolted in, while the tbird has the lockring. Is the tool mentioned in the manual worth trying to find? Any tips on this procedure?

Is there an O ring in the filler tube that needs to be replaced? Remove the tank with filler tube attached or?

TIA

From a recent post:
"The fuel pump is almost drop in. You may have to take off the filter sock from the original pump and put it on the new pump, depending what kind of pump you get. The socks that come with Mustang kits won't fit. This is not difficult. You will want to get a new gasket for under the flange that the pump is attached to. If you old lock ring is really rusty, a new one would be wise. It can take some finesse to get a rusty one out without damaging it."

You can remove the locking ring the really soaking it well with PB Blaster. Brush and vacuum all the crud away first. If it's really rusty get a new one, same for the big diameter flat gassket that goes under the pump flange. Anyway using brass or wood "hammers" and screw drivers or wood stick, you can gently beat the ring loose. Ty tapping it gently straight up in down to break the corrosion loose.

Yiu need to take the filler neck loose inside the gas door. pray a little lube around it where it goes into the tank. Once the tank is down a little ways you should be able to seperate the two.

An ATV/motorcycle jack works very well at supporting the tank when you are dropping it and at raising it again and holding it up while you are wrestling with the straps.

Get the tank as empty as possible. For me it made all the difference in the world.

If the old pump will still pump, disconnect fuel filter outlet, and attach a few feet of hose to the nipple on the filter. Run other end of hose to gas can(s). Turn key to RUN, and ground the fuel pump test terminal on the EEC TEST connector. Pump will run and pump out all but a few quarts of gas.

By all means get the tank as empty as you can! It is amazing how heavy a gallon or two can get when it sloshes from one side to the other while you are doing a balancing act under the car. Also, be very careful pulling the tank away from the filler tube, and when reinstalling. The rubber grommet/gasket does not exist in nature anymore! Mine tore ever so slightly and when I reinstalled the tank the gasket was partially pushed inside the tank. I discovered this when I tried to fill the tank with some expensive 91 octane leak detector (Gasoline). I just loved draining a full tank just to fix something that wasn't broken before I changed the pump! By the way, the pump was a snap! Good luck.

Replaced the fuel pump today with the walbro 190 lph pump, not too bad of a job. Everything came apart and went back together without any difficulties. Filled it up and no leaks anywhere [Image: smile.gif]

Kit provided with the pump had everything needed, new strainer, O ring, fuel line and clamps, fuel line clips and wire harness. All together $95.55 delivered.

It's good to have fuel pressure again... I picked up this care about a month ago and It would always fall flat on it's face under boost. Now it actually makes a little power.

Thanks for the tips...

PS, this is my second TC... the first one self combusted in the Mirage parking lot in 1996. Only good thing about that is I was able to get a new 96 Impala SS. When I brought the tbird home the Impala got jealous and killed it's fuel pump. I think the tbird was watching! 2 fuel pumps in one month... geese! I think my daughters 88 Mark VII is next... it's acting up when hot... Only good thing there is she is always low on gas [Image: wink.gif]
