changing the fuel pump

changing the fuel pump ***update****

I need a new fuel pump. Should I do it myself or pay $100 to have it done? I think I am above the average schmo when it comes to car repair and knowledge. I have two jack stands and a small hydralic jack. That should lift the car nicely and lower the tank once removed. This is my third fuel pump in this car, so I know the straps/hangers have been removed before so they should not be too hard to remove. Anything else I should know/think about? I am ordering a new Walbro 190 on Monday to replace the factory one I have now and hopefully fix the 556 code I am getting.

Thanks

Personally, I would pay $100 for a competant mechanic to do it for me. It's just not a job I like to do. This is especially true if the tank as any amount of fuel left in it.

If you do it yourself, find a friend to help wrestle the tank down and then back up afterwards.

Do a search for "fuel access" or "fuel door" and you should find some instructions on how to cut a hole in the floorboards under your rear seat to access the pump. This will make the job uber easier.

Speaking of which, I need to find that thread myself and do something with it....

*edit* Here, I found it for you, 'cause I'm just such a nice guy.

I would not go with a 190lph pump. With a Gen 2, I would go no bigger than 155lph. A 190lph will make the car run lean... even a 155 makes it run a little lean. I know this because I have some extra gauges and a TwEECer RT. I lost power because I was running so lean. I cut an access panel the second time I replaced the pump.

Since your straps are in good shape and have been removed before, you should have no problem using the conventional method of dropping the tank and as opposed to cutting a hole in your floor board.

I was able to drop the tank on my SHO by myself without any issues. One thing I did was to use some large blocks of wood to help keep the tank propped up a little while disconnecting everything. The blocks also helped when putting the tank back.

You will find around here pretty much a 50/50 split as to people who cut holes in there SHO to access the FP, and people (like myself) who drop the tank. If (when?) I have to replace the pump again, I will drop the tank again.

In any case, this link can help you whichever you decide:

what kind of mechanic will install a fuel pump for 100? is that labor only or is that for the pump cost as well? The 190lph is 85 bucks as it is. 15 labor? wow, if the guy is worth a toot sweet I would have him do it.

I just finished this job on my 89. A couple pointers for you...Disconnect the hose to the fuel filter before you begin to drop the tank. I broke it and it was a bitch trying to find a new one. Secondly the bolts to the tank are probably rusted, so spray them with pb blaster thoroghly before starting. Be careful as I broke a bolt trying to get it off. As stated before its not a hard job as its only 6 bolts and the gas tank can come down, just make sure everything gets disconnected before you pull it all the way down. Replace pump, be sure the o-ring gasket is firmly in place, and reinstall.

Goodluck!

Well I just installed a new Wlabro from www.APEusa.com. I decided to do it myself and save the 100 bucks. Great idea. It took me about 2 hours to do the whole thing including dropping and removing the entire fuel tank. No real issues encountered. I even did it myself. Now I know exactly how much fuel is left in the tank when the light comes on. Quite a bit. I started the car afterward and it seems to run fine. I then checked the codes to see if I was still getting a 556 (primary circuit fuel error) and it seems to have gone away. Lets hope this fixes my bucking bronco problem of late. For all those who responded, thanks for the help....
