Need a new fuel filter cap

Went to change my fuel filters today and the cap for the bottom one in the frame rail will barely come off. So, need a new one. Are there any upgraded ones out there that make this easier than the plastic one that rounds off easy? I've found lots for the one under the hood, just haven't found any for the frame one. I've already upgraded the drain thingy to make that easier.

The cap for the hfcm is the same as the oil filter.

Use a 6 point socket, not a 12 point.

Thanks guys! Now to get a new one ordered as well as a 6pt socket. Funny how I have no problems with either the oil or fuel filter caps under the hood. Only the HFCM. It's been getting harder and harder to screw on/off the last few filter changes.

Well, crap! Already ordered and they've shipped. Too late to cancel. I like those riffraff ones a lot! I'd have a hard time choosing color though, lol. First world problems I guess. Next time I suppose.

You may also want to flush any crud out from the HFCM threads.
Diesel would be an easy pick and just set a pan under it to catch
the drippings. I use one the oblong funnels stuffed under the HFCM
to direct and fuel coming out into the pan.
