13BREW Engine Rebuild - Parts List

Like a Jigsaw Puzzle...So Many Parts

A few of the parts used in my little "rebuild" project

With so many parts to keep track of I did my best to account for all the pieces. Because this was a rebuild that took nearly two years I do not profess that this is comprehensive but it should give you an idea of what went into my effort. I hope it can be of use to anyone looking for similar equipment. The list inludes the part, a more explicit description, the part number (if I could find it - I'd verify these if you wish to buy the same part - some of my reciepts were hard to decipher), the retail value of the part (remember I buy **USED** so chances are I paid considerably less and the shipping is not included), and a good source for a new part or information on the parts source.

Fuel System: Fuel Lines and Filter

All the new Earls fittings I bought at anplumbing.com. The prices below are all for new fittings. Most if not all the reusable fittings I installed were used and bought of eBay for significantly less. Hint: use eBay to buy in bulk, for example I picked up a used Holley FPR, one -6 straight hose end fitting, eight -8 hose end fittings (various straights and 90’s), two -10 hose end fittings, and two tube nuts. All for $55 shipped. This lot, new, was valued at nearly $220.00. Or a lot of fourteen various -8 fittings and hose for $109 shipped. Consider the -8 hose ends run about $25.00 each that’s a savings of over $250.00. The fittings I didn’t use I will resell and more than likely make up the initial cost of the purchase!
