I think they are 3/8x18 or 5/16x18, not sure of the length.You should be able to get them at any parts store. A speed shop will probably be able to get you the correct bolts too.

Re: mech fuel pump bolts
We're talking mounting the fuel pump to the plate, or the plate to the block?
I'd guess 5/16NC. They have undersized heads too. Not sure if a normal sized head would work, allen capscrew would probably fit. Come to think of it, it might be 3/8NC though (3/8-16).
The ones for the plate to the block i'm pretty sure are only 1/4-20 though.

Plate to block are 1/4"NCx1/2".
Pump to plate to block are 3/8"NCx1". Many factory bolts were reduced hex head, makes it a little easier getting a socket in there.
http://store.summitracing.com/egnsea...=KeywordSearch I like the ARP a lot better, Mr. Gasket doesn't have reduced head (and MG is on my "list" for other QC issues as well).
