Jurjen's check valve

[jim]

Today I went to 4 parts stores and a large hardware store.  Most were of no help at all.   One ordered the valve but it had female ends.  I didn't want to deal with trying to find nipples.  There isn't much room anyway; valve and nipples would take up a lot of the hose.

Hallo Jurjen,

Een paar weken geleden heb ik een aantal verouderde vacuum en bezineslangetjes laten vervangen.
Wat kunnen de problemen zijn/worden als de check valve niet meer in het benzineslagetje zit?
Heb je enig idee waar ik een nieuwe check valve kan kopen? Mijn donoreagle staat in de stalling, mogelijk vind ik daar de reserve valve.

Hi Jurjen,

 A few weeks ago, I have some old vacuum tubes and gasoline replaced.
 What problems can / will be the check valve is no longer in benzineslagetje?
 Have you any idea where I can buy a new check valve? My donor eagle is in storage, may I find the reserve valve.

I found the valve on ebay.  I'm waiting for an answer to my question about shipping, but I plan to buy 2 of them regardless.

That is a pretty good translation! Benzineslangetje = fuel hose.

Have the original set-up again, but it is draining back to tank again. So will will put my new check valve back in.

The spring inside has weakened over time, try to take it out and pull it "a bit" to strengthen it slightly and / or the ball and / or seat has corroded, take apart and clean seat / replace ball.

Jurgen I keep seeing that in-line check valve That you found in the factory fuel hose and just can't figure out what where they thinking when that set it up hidden like that.
Any chance the original check valve is design to slow down the fuel return insted of completely stopping it?

[Jurjen]

I think that it works like a cheap and dirty pressure regulator like used in EFI systems.
After switching off the hot engine it will also allow the vapours to escape to tank.
Adjustable pressure regulators are available in the 1-7 psi range, but expensive.
It will behard to get theold check valve out now, so I will leave it in and add my new valve.

You can also find these check valves in 81-83 Concord/Spirit. Also note that the TSM for 81 states that 81 is the first year for these.

I bought a check valve on ebay Sunday, received it Wednesday, installed it in the 88 Thursday night.  Cranked it and let it run a few minutes.  I'l wait a couple of days before I start it again.

[jim]

I don't know what to think.  The first 2 times it started so quickly it startled me.  I let it sit a day and it was hard to start, back to its old ways.  The next time it started immediately.  I'll try it again tomorrow after letting it sit overnight.

I'm running the Motorcraft carb and an Aeromotive adjustable fuel pressure regulator. I no longer have the check valve and use a standard fuel filter. My car can sit a week and I'll give the accelerator pedal two pushes and it cranks up immediately. However, when warm, if I let it sit for more than a couple minutes, I have to crank it for a while before it starts. If it sits for more than a half hour it will start up like normal.

This may be due to the intake being directly above the exhaust manifold.

I have often wondered that. However it doesen't happen to the other 2 DD's. Just my stroker with msd fired ignition. 21?? Somthing carb. So that to me rules it out. Also I had an 80 kee that never ever started hard.

The 88 sat for 6 days and started immediately, and again after sitting all day while I was at work, and even better this morning after sitting over night.   I have to believe the check valve made the difference.  That's the only change that has been made.
