Link to Restorer article on 40083 fuel pump rebuild

[Michael M.]

Can anyone provide a link to an article in a 2010 issue of the Restorer on rebuilding 40083 fuel pumps? I bought the CD containing the past issues of the Restorer just after I joined, but it stops at Vol.36 just short of the issue I need. I believe the issue I need is Vol. 37, No.1 or No. 2. I have the actual magazines from when I became a member, starting with Vol.37, No.3, but it looks like I'm missing that one issue with the article I need. Actually, I might be missing a couple of issues, but I need the one article on that fuel pump. Figures. It's Murphy's law, which counts double for Murphys. There was a link in an old thread on the TDB, but it doesn't work anymore.

Thanks for any help I can get on this. Rebuilt originals are so expensive! It works fine now, but who knows if it was ever done before and the hose from the line to the pump is looking really bad. It's time.

Thank you Vinnie, I got it. Great article, BTW. And thanks to Joe Ciaravino for writing it. It looks like fun. Hopefully it comes apart nice and easy and goes back together that way too.

I took the car out for a blast on Monday, before the snow came yesterday, and I noticed the engine breaking up or cutting out a little bit when I pushed it over 4,000 rpm. After thinking about it, it's probably the sparkplug wires (carb was restored 2 yrs ago, dist cap & rotor new last year), but the fuel pump had been on my mind anyway. In fact, I ordered the kit from Hal Houghton last week. It's a good time to do this stuff. I just gotta get the heaters going in the garage. I think I'd rather join you guys heading to Kissimmee, but not this year.

Mike, Make sure the rebuild kit you use is for ethanol. John

John, you raise a question I have had for a while...and discussed with other NCRS guys. Is this ethanol junk gas killing our tank sending units, O-rings, etc? Should we avoid using it? Odd how my all original 67 L79 car all of a sudden started weeping gas from the O-ring or sending unit after I put about 16 gallons of gas in it....and this after 44 years...coincidence? I am not sure....Any thoughts? Thanks. ARA

Thanks John. I believe the kit that Hal sells is ethanol compatible. Whatever is in there now now seems to function fine. I just don't want it to go down on a long trip and I don't know what's in there so I'm gonna rebuild. I assume (maybe wrongly?) that if it was rebuilt once that they would have changed the hose from the gas line to pump. It looks SO bad that it might be the original hose. So, time to upgrade.

BTW, I know there is "fuel line" grade hose, but is there something better I should be using? It is kind of a vulnerable spot. Although, the one on there now sure looks to be 47 yrs old. As long as it looks close I'll go for a better one if it's that much better.

Michael, I found some black high pressure fuel injection hose at Carquest for multi-fuel use. Just wipe off the writing on it with acetone.

Thanks Dan. I'll check it out. Sounds like it has to be stronger than the run of the mill fuel line hose.

Dan, The Car Quest hose you bought is absolutely perfect. Now I don't know about judging but it will hold up to ethanol.
When I did a few seminars on ethanol I brought buna rubber o'rings & viton o'rings, original fuel hose from the old days, CQ fI hose, etc.
I brought along jars and beakers and used ethanol in all of them. While the audience was listening the crappy rubber parts were swelling up like a donut.
The viton rubber parts were not hurt at all.

Story: The 63 FI's use a PCV hose with a diamon pattern on it. I found a small supply of this hose at a flea. Problem is the hose I found is only 7/16" ID.
It should be 1/2" ID.. So on a restoration I cut the proper length hose for the PCV valve. Take it outside in a can with ethanol. Soak it for two hours max. Bring the hose in and wash it in hot soapy water. Put it on the pcv hose and it fits perfect.
The ethanol fuel pump rebuilt kits are not for judging. They are for driving. Gaskets aren't even close. But the kit does the job.
Ara, I am not going to start talking about the sending units as don't want a big discussion going with negative replies as too busy.
But you may have somet hing there. MY NOS 63 sending unit had or has ( I sold it) a large rubber biscuit in it. Looked like something a baby with cut teeth on.
Anyhow I often wondered how long it's going to be before the ethanol starts trashing that rubber part???? John

Thanks John, it works fine, still soft after 6 years. Michael, remember to change the tank sender to the rear fuel line also, it will be rock hard!!!

Re: Link to Restorer article on 40083 fuel pump rebuild

Thank you Dan. There's a CarQuest nearby and they have that type of hose in stock. I'll be sure to get enough to do the rear as well.

As for ethanol in gasoline, I wish I had a choice. That's all they sell here in NY.

My sending unit or fuel gauge is malfunctioning as well. Shows full when full, but shows almost empty when 3/8 full. Not sure which it is. I guess I should start another thread asking that question. It's on my to do list. Maybe it's time to drop the tank and do the whole system from end to end. I'm hoping it's the sending unit. If it's the gauge, that's a whole different deal. Why do one without restoring the whole cluster. And everything else works fine in there. It just looks old and faded.
