testing a manual fuel pump

[J-Gaz.]

Perfect - Thank you Cusser.

I've got a feeling I may be having the shop go through my fuel system, tank, filter if applicable, cleaning out/ flushing the steel fuel line, back to the Fuel pump, replacing the base and hoses along the way - then testing the fuel pressure... You know, basically reducing the fuel system! ha!

If it's got debris in the fuel tank, it likely goes all the way back. May as well freshen everything up.

Wish it was something easier, but it usually never is...

Well...replacing the bake light piece is *really* easy and you could potentially save hours of labor from a shop going through systems in details...sometimes you get lucky and it's the simplest thing in the chain....

Awesome Cusser - this is great to know.
I may just add one as well.

When you resurrected yours had you run into an issue with gunk in the steel fuel line in the tunnel? Or did it not really need to be addressed?

[J-Gaz.]

@Vamram, you talking about this base, correct?

It would Swell up and inhibit the pushrod from functioning?

Copy Hot Arizona 🤣

Yeah, I guess the temperate northwest and ever-present marine layer we've got here in SEA treats cars differently... 🌥️☁️🌧️🌧️

Clean or replace tank and its screen, blow out main line to engine with compressed air, replace all the soft lines and filter. A friend and I just did that to his 69, it acted the same way, rusty tank, screen was partially plugged, they get that way if they sit to long especially in humid climates with out a full tank or properly treated one.

Sounds like the list I was just making.
Appreciate it.
Was the job you and your friend did fairly easy?
How long did it take?
Did you guys measure the Fuel pressure too?

Mine was stored for a number of years not really driven, but I always fogged the motor and treated the gas.
I probably could have done a better job.

The guy that owned it before me I don't think kept very good care of it. He was the local postmaster and got it to drive to work when it snowed - but we had a few years back then with no real snow, so it sat.

That was in the late '90s to early 2000s before I got it in 04. I'm not sure when he actually bought it though.

When I had it, I spent most of my time learning about and rebuilding the motor - making lots of mistakes along the way. Still isn't perfect, but she wants to run most of the time - accept for this stinking hiccup/power loss.

[J-Gaz.]

Challenge accepted.

Honestly, I can't tell from the photo that the old Bakelite has a smaller ID than the new one - but if that's what fixed your problem, and it's $5 bucks, could be worth doing regardless.

I appreciate the info.

Does anyone have any more documentation of the bakelite swelling? Seem's like if it was common (Even if it takes 40 - 50 years, or only happens with ethanol in the gas) there's be some more info on it. I've posted another link from the forum down at the bottom, but that's all I've found.

Maybe that's all we need... But they talk about the outside swelling and putting pressure internally on the pushrod, not necessarily the ID shrinking. Same end result, regardless.

Pulled my Fuel Pump Stand this evening, and it is tight coming out.
I don't have much of a shop, but I think I'll order a new one and grind it down, leaving the original as a backup as is.

I tried to drive it last weekend

I thought I could get one slow in-town drive in while I waited for parts.

I was wrong.

and had to get towed home... It just wouldn't run.

I got the Fuel pump bakelite stand from Westcoast metric earlier this week, along with gaskets, and finally had the chance to drop it in.


The Fuel pump bakelite stand dropped right in like on the Chris Valone video and mimicked the Bug Me video posted above.

Sadly the car didn't take to the repair.

Wouldn't start or run at all. Same as this last weekend.

There may be something more sinister at play.

Can't check the fuel pressure if it's not running...

Any ideas on what to check next?

Appreciate it.

I pulled the fuel pump and it appears to be weeping the tiniest bit of fuel where the pushrod would engage the pump.

I guess the only next thing I can do is replace the Fuel Pump and see where that gets me before I have to take it to the shop.

Any recommendations where I can pick up a quality fuel pump?

Regardless I think I've got to get the steel fuel line cleaned and add a tank filter.

Great - thank you!

This is what I use on my 1970, with factory 108mm fuel pump pushrod.

Folks will cringe about a made-in-China fuel pump, but it does have clips on the horizontal pivot rod WHICH IS VERY IMPORTANT !!! I've used this over 3 years now.

Appreciate this Cusser.
I just ordered the short generator fuel pump from JBugs (Made in China),, the one that was on there was the Brosal with the curved output.
The Brosal was on there when I bought it in 2005 or so... and I reused it when I rebuild the motor a couple of years back.

When I replaced the fuel pump stand a couple of weeks ago, it seemed like there was a little fuel coming through the fuel pump down onto the tab that the pushrod pushes, so I just replaced the pump. It was one thing I could do to try to isolate the issue.
Now I think my fuel pump is like yours.

Both short pushrod styles though designed to fit generator cars.

Installed it late last night.
I also swapped the fuel filter.

Haven't fired it up yet.
We'll see if that does the trick, if not... to the shop I guess - I can't do much here in the space I've got here.
