Made a mess of the piece of frame that connects each side of the frame.

I was attempting to install a bulkhead on each side.

One is was higher than the other and I drilled again and its to low..

AGHHHHHHHHHHHH

Can I fill with weld and redrill the area?

can't tell by the pics how big the holes are, but if they're much bigger than a half inch, i think i'd try to find a piece the same thickness as the frame & make a small round patch to fit inside the hole & weld that in the hole flush with the frame. bevel the edges good, & you will get a full penetration weld. it might be a PITA, but the finished job will be much nicer, & you won't put as much heat in the frame as you would by welding the hole shut. if they were 1/4" or say even 3/8", i'd say weld 'em shut. if you want to re-drill after welding, get yourself a centerdrill to start the hole. it will be much easier on the drillbit.

The holes are for a 5/8" fuel line.

How thick is frame there?

I used one of those Christmas Tree drill bits..

You should be able to weld it.

It's not a hardened steel truck frame.

I've welded the crap out of mine over the years, fixing the cracks from when it used to race back in the '70's.

It appeared to be fairly soft...

Yes, I race this car......Im upgrading from a 1/2" line to a 5/8" line...

I just the second hole (one below the first one) to low.....

I could use what I have...but Im a perfectionist....

If I put a patch or fill........Im assuming drilling a new hole...would not be a problem even if I drill though a welded area?

Ya it'll drill but weld is some hard stuff, as Jim said drill a pilot hole.

Oh..Ok..I got you now.

Use a pilot hole first and then the Christmas Tree bit...

How big should the hole be?
