Bought a Stant indicted for a 2008 E250. Cap causes significant vapor leak when stopped and a 'gross blockage/leak' message from the computer.

Comment ?

 

I would return the Stant and in its place get the Ford part or its equal.

While Stant is a well respected part brand perhaps in this situation their products aren't ideally suited to the called-for application?

What prompted the replacement anyway if I can ask?

 

Summit sez a 2008 Ford e250 5.4 uses a 10503 Stant.
I have 2 Stants and one ?...None work as lighting the fuel warning LED or smell.

Odd is there were 2 prior locking caps, both worked. I lost keys for both at no time for searching so pried the caps off with vice grips.

I look to the fuel filter for replacement this week.

Two working and 3 not...could be a tertiary cause.

Ford does not offer a locking cap for an E250 listing nor does Stant sell a metal capped cap.

Using a locking cap partly solves a security problem. A thru gas door into cargo threaded rod is probable.

Drilled/tapped the gas door for security screws. Next trip to Walmart, the mechanics poured gas into the door area.

 

2008 E250'S STANT cap is a 510 not 503...


as of this week, in theory as cap is in transit.


503 is a 2001 cap.


so when you glide into the parts store for a locking cap..beware !

 

510 STANT locking gas cap.


Summit catapulted 2 my way. One is mounted and great ! doesn't leak. Not a whisper of toxic injury causing fumes.


DUH,,,the new cap is of course the same as a Ford OEM non-locking cap 'cept the top which has what on it ?


The 503 is not a duplicate of a 2008 ...cap.
