My fuel pump died when I was 200 miles from home. Luckily it was nearly in front of the Ford garage in Groton, SD. One aftermarket fuel pump and 24 hours later it is back on the road. The new pump is louder than the old one (which, obviously, was not making any noise at the end). I won't be home until tomorrow night and won't know what they put in until I can look under it.
My guess is that it is not a Bosch pump. Does anyone have experience on how long various aftermarket brands last ? Is there any brand I should change out ASAP, i.e. the URO of fuel pumps?
Thanks
Greg

Hi Greg,
According to my IPD friend, they last very long time with 1% failure probability based on their sales history. It looks like they carry these following brands; Delco, Bosch and PPS.

The noise may be caused by the coupler/bridge between pump and filter. It can easily kink, it's tricky to tighten it without bending line. I mention it because it happened to me on my 740 recently, look in 700 section for details, or search my name and fuel pump.
If you still want a Bosch, look at Autohaus Az for great price with free shipping.

Very real possibility. That sort of goof occurs mostly from folks who remember changing a fuel filter being a Saturday afternoon pleasure taken while marveling at the complexities of a carburetor. Banjo bolts and nylon lines were not involved.
If a pro did this, I would not be surprised. I just saw a video where one recommended clamping this same nylon fuel line completely shut in order to isolate the cause of leaking residual pressure in a fuel rail. One of the reasons some of us want to do our own work, instead of paying someone else, we know how it is done, even if it is wrong.

Why does someone believe you when you say there are four billion stars, but check when you say the paint is wet?

With a noisy main pump, I'd check that the in-tank pump is working. If that has failed, then you can bet on the main not lasting 50,000 miles.

I'll give it a listen while I'm checking things. The intank pump was probably working just before the main pump failed. I had just stopped for gas and put in 12 gallons. The car idled fine until it wouldn't run.

Hi Greg,
Your in-tank pump can be dead for years and you may never know. In that time, as Will notes, your main pump will wear and become less able to suck the fuel past the dead tank pump. The reputation of non-Bosch main pumps is indeed trashed very often, but I can't offer any corroborating information. Airtex is usually the one that is mentioned, but on the other hand, I've been quite pleased with Airtex in the tank. Of course that pump is an entirely different challenge to make vs the main pump, which needs high precision in its roller cam unit for wear life.
You should be OK until you get home and into the summer. Read this in the Spring:

Hi Art,
I read that when I was preparing to replace the fuel sender a few weeks ago. Thanks for carefully writing up your investigations.
The in tank pump sounds like it is running (I stuck piece of heater hose into the filler neck). The pipe between the filter and the main pump is fine. It looks like they did a reasonably careful job of replacing the pump (except for leaving one of the fuel filter fittings a little loose).
The new pump is not a Bosch pump. Without removing it I can't tell if it is Airtex or some other brand. Besides the main pump being louder than the old one, I see that the mechanic cut off the Bosch connectors and crimped on a couple of rings. I'll have to salvage the wires off of my parts car when I replace the pump.
I'm going to have the fuel tank down when I replace the fuel filler neck so I'm wondering if I should go ahead and replace the intank pump while I that close.
Greg

Oh, okay. From what I read in your posts I suppose what I would do in your place is nothing -- with the main pump/filter.
Of course, I cannot hear the pump, and I don't know how your confidence in it or the job of replacing it bears on such a decision. More detail about the loose filter (goes to that confidence I suppose) might help. Was it leaking? Or did you just decide to wrench on it and it felt like you could move it a bit tighter? Which end was loose?
As for replacing the tank pump "just because" did you already have the sender out or was that still in the planning stages? How was the connecting hose between sender and tank pump? Is it possible to fix the leaky filler pipe with a wrap of some sort of fuel-resistant tape and/or epoxy? Or did you get that one Oleseahorse saw on ebay? I have no experience here.

Hi Art,
I have already replaced the sender. The rubber connector tube looked good. I used fuel tank repair kit epoxy on the fuel fill pipe. The hole was right at the ridge where the o-ring and clamps fit. Apparently I did not get the joint smooth enough to be fuel tight. I found a good used one on eBay ( actually someone else on BB found it and pointed it out). I bought a new clamp and o-ring so once we get back from out west, I'll replace it.
The rear fitting on the filter was leaking. It was a little more than finger tight, but needed another half a turn.
Aren't impact wrenched great for getting things apart ?

Finger tight? Really? Sounds like one of those forgetful mistakes I make now and again. They cause me to re-evaluate how long I can continue making my own repairs to things my family's safety depends on.
Yes, the rattle gun is to me an essential for the fuel filter change. Trying to use wrenches to counterhold that filter when loosening or tightening has, in my opinion, destroyed more of those short nylon hose assemblies connecting the filter to the pump than any other goof.
With time, you will get the feel of the impact tools so they will be useful installing as well as taking things apart. One of the hurdles to that end, I think, is learning to watch the socket as it advances the bolt to correlate that with the angle you achieve by turning one by hand with a ratchet. Otherwise, with varying air pressure and little experience, torque is sometimes difficult to interpret.
