403 Olds Fuel Pump Mounting Hardware
« on: June 12, 2018, 07:07:44 AM »
Hello everyone, I had a fuel pump mounting hardware question.

I replaced the fuel pump on my 79 Trans Am with a 403 Olds and when I was taking off the top nut, the entire stud came off the block.  I looked at the threads and they looked a little damaged so I figured why not replace that stud but the problem is that I cant find it anywhere to purchase.

Can anybody point me in the right direction?

Thanks in advance!

I poked around the interwebs a few minutes.  All I could find is a kit from Mondello sold through E-bay.  Not cheap.  Not sure the link will work but here goes:

if yours aren't bad you can just chase the threads with a die.  If the pic in the link is correct there are coarse and fine threads

Now the description says Oil Pump Stud Mount kit, but are these the same studs used to mount the Fuel Pump?

OOoooppppsss!    :oops:

That would explain why I could not find "FUEL PUMP" studs on the Mondello website - only Ebay.

Unlikely in the extreme that the fuel pump and oil pump use the same studs.

Sorry about that!

Why can’t you just use a bolt?
