1994 f 350 turbo idi o-ring fuel leaks

[ramrod]

for the past 4 years in the months of april and october i have to replace my injector o-rings. the fuel that leaks accumulates at the back of the manifold sloshes out when you hit the brakes. anyone else having this problem? could the o-rings be shrinking or deteriorating or could maybe the tee's need replacing?
why only at these two months of the year? seal quality or season changes?
i replace all 16 o-rings when i do it, though not all of them have leaked
factory ford parts used

It is odd that they only leak at those times, but that is when the transition between winter blend and summer blend occur. You do want to change the caps as well, as they distort over time and heat as well. Rule of thumb is to do the caps any time you do the o rings. You can find full kits with hose, caps and o-rings for a decent price if you look around. Got my last set in the territory of $30 on ebay I think.

Pensacola Diesel sells the return line kits for 19 bucks. Been there, bough that lol. http://pensacoladiesel.com/89-93-7-3l-injector-installation-kit.html

What O-rings are you using also, because that will also make a difference.

It may well have been Pensacola I got them from.. return line kit is the search.

As stated, the o-ring type itself can be an issue.
