I must be doing something wrong. I have had my 96 for 2 years and it seems like every year the modules need to be replaced. Purchased the truck and had the cross flow issue - front to back and bad pressure in the back. So changed both modules and both tanks. Blew out the lines from the fuel filter back to the rear of the truck and installed new fuel filter. Everything ran good for about a year. Front pump was LMR supplied and rear was Spectra Performance. Then both decided to have low pressure front was like 22 psi and back was 10 psi. Both pumps did have full voltage to pumps. I changed both of them to Delphi and all was well. Pressure running was a good 46 psi on either tank and tested them over the weekend and still running a good 46 psi. Key on engine off was I believe 55 psi front and 57 psi rear. The problem is crossflow from the rear tank to the front tank. I know that all the pumps I have installed were manufactured in China. I do not like dropping the tanks and the bed has a lift gate so that makes it a little rough to do. Although I am getting pretty darn quick at dropping those tanks. Anybody have any suggestions on a pump module? I will probably get another Delphi in the mean time under warranty and replace it. Yes, I do change fuel filters regularly and I use Wix. I even change the tank select switch with a Wells, just because. The oe Ford Pollack one was working as far as I could tell with my multimeter. Anybody happen to have a part number for a Motorcraft 96 F150 inline 6 midship tank 16 gallon? Motorcraft part number for rear tank 18 gallon? Thanks, and I am trying not to rant too much about the quality of parts today. Still like the truck and not going to sell it. It is family.

 

Not to add to your rant, but I relate. It's just the way it is. Seems like everything is made to the lowest standards possible.
Anyway, I don't have the same pumps as you, because my truck is an '88, but maybe search junkyards for the external check valves. I see manic mechanic post about them a lot, and recently, on another forum, a new member discovered one which was already installed on his original fuel pump. Maybe there are more like that in junkyards

 

I have always had good luck with pumps and I have used Delphi and Spectra in the past. Then just a few months ago I did pumps on my neighbor's truck (91 F150) and went thru 3 on the rear before I got one that worked. Crazy as this is, the one that worked and is still working is a no-name cheapy from Amazon:


The reason I chose to go with this one after 2 bad Spectras and a bad Carter is because I have one of these on my ranch truck and it's been in there a couple of years with no trouble. YMMV of course.

 

I tell you what, it must be a conspiracy. Went to the link and Amazon clearly stated "can not be shipped to your address due to local laws or Amazon policy". Good thing I have a good sense of humor about things. Still not selling the truck.

 

I looked at your profile. Is that California or Canada?
I see it's California... Bummer

 

Junk yard is a good source for new modules. (lots of new parts sadly)

It'll have gas in it even if tank was drained.

Drill battery & a couple wires & if good it'll shoot gas quite a ways.

Don't set yourself on fire of course.

 

CA used to be a very good state, but some individuals are trying their best to make life a touch bit more complicated than it should. I have been there all my life, except for a few out of state vacations. Used to be able to get anything automotive and do anything automotive, but the freedoms and sources have slowly and steadily eroded away. Wrecking yards were at one time plentiful and a treasure trove, but have almost gone by the wayside. Oh well, got to love a challenge.

 

It's sad to think you invested so much of your life into a town/state/country and that it's all gone down the crapper. Life is not fair it never was. Without a doubt, it's a challenge for sure.

China is not the problem, it's Spectra. There is a lot of stuff made in China that is good. Good companies sell good products from China. China does not care what the quality is, there is always a cheap a$$ US buyer willing to hand over their money to save a few dollars. When will we learn?

If there was not any good brand modules, I would look for something used. Sadly, pumps do not last forever so if you get a used one, you might want to invest in a good/new pump before you throw it in.

 

True that. Sometimes we are our own worst enemy. Best thing to do is learn from the past and try to not repeat the same mistakes. I believe that I will warranty the Delphi and try another Delphi. At least the front module will pump and pressure is good. I will use the front tank first, then use the back tank and let it cross flow to about 1/4 tank and then switch back and use the front. Don't want to do that too long because I will get lazy and not want to repair it the right way. 4th of July is coming and that might be a good time to do the work, if something else does not pop up first.

 

I've replaced about a thousand pumps by now, and you get what you pay for
I've used everything from a 58 dollar Ebay pump to a 998 dollar GM pump
Some Ford flex fuel pumps are 1000 dollars too
BIG fan of factory pumps myself, but supply and demand are the rules the game

 

I agree, supply and demand does dictate what is going to happen. That is why the $58 eBay pump is sold more often. The good manufacturers stop making pumps because who wants to spend good money for a good pump?

 

No argument here. I try to use original equipment when available. It had to make warranty and not making warranty costs the manufacturer money. If oe is not available, oe supplier to the oe is good. Sometimes aftermarket is only what is available. I try to find oe part numbers and search the web for someone who has new old stock. My local GM dealer has been extremely helpful to me in the past. The local Ford dealer owned by the same guy as the GM dealership is okay. It really depends on the parts guy at the counter. I try not to drop a lot of requests with them for obsolete materials. I do this because walk in customers are not really that high volume of sales. Sometimes they can locate obsolete parts and sometimes it is just last known number. On a good day, some have looked at dealer to dealer network for me and handed back information as far as part number, quantity available, location , and price.

 

A good parts counter man is as difficult to find as a good mechanic. Most of the people just look at the computer screen and tell you what it says.

I had a parts manager one time told me the part was NLA. WTF? The car was 2 years old under warranty. I told him he was an idiot. His answer was 'That's what the guy on the phone said'. I told him that guy is an idiot too. Yeah, I was not easy to deal with, fortunately, I could fix cars.

 

Yes, if that. There are still a few good parts counter people at the dealerships. The discount auto parts places are another story. There are some counter people there that do have a clue and are okay, but then there are others that are a true gift. I always enjoyed it when I was asked if one of my first gen Camaros was a 4 door or station wagon and I would quickly say that of course it is the convertible hard top station wagon. That all came about because I was trying to get valve cover gaskets. Then there was always telling them that the 68 had a 302 engine and they would say that there was no way possible because that is a Ford engine, but I guess they never heard of a Z/28. Then the 70 Cougar had a 351 Cleveland and I was told it could not and it had to be a Windsor. Things that make one laugh. If I wanted to really mess them at that point because I was frustrated : Corvair radiator, VW Beetle or Karman Ghia radiator, headlight gasket set, muffler bearings, and then later on halogen fluid.

 

There are good people everywhere. All shapes, sizes, colors, and beliefs. It's just getting harder and harder to find them. Sometimes we limit our search because we 'think' they have no clue. A lot of good people are being replaced by AI. That prevents people practicing/honing their critical thinking. That is why people no longer second guess the computer.
