look for a leak in
your supply lines.



Any advice on how to do that?

visual first, are they wet?
Check all nuts for tightness.
Clamps for tightness,
hoses for leaks or cracks.

It could be as simple as a banjo bolt washer that has compressed....

As I cannot see your installation, I can only give generalities.

I've seen it be as simple as a fuel filter gasket with a small pit in
it. The seal worked under pressure, but left a bit of air into the
system when everything cooled off and the pressure dropped.

Do you have any high points in the system where air could collect?

Do you have a mechanical fuel supply pump or an electrical one?
Hoses or hard pipe from the tank(s)?


If you have a leak, it is currently a small one from your symptoms. If
it was major, you'd have real trouble starting at all.
