Engine Overhaul and Recirculating Electric Fuel System
I don't post much here, so I figured I would share what I've been up to lately. The vette had been neglected for close to 6 years while I lived in various apartments without a garage. Now I've moved in with my girlfriend, and have a suitable man cave to do my projects in.
This summer's project was an overhaul to address a crushed oil pan and an un-traceable coolant leak. Also, installed an electric fuel pump system, with a recirculating flow design using AN hoses.
The fuel system was the biggest challenge. My build involved the following:
- RobbMC return style sending unit for stock tank
- Aeromotive pump
- User-servicable filters, 40um and 100um.
- AN -8 hose for return and supply, using the stock fuel line pathways along the passenger frame rail
- Aeromotive pressure regulator
- TYCO weatherproof relay, soldered/shrunk AMP connections end to end
- Holley oil pressure safety switch
- Countless Russell and Summit AN hose fittings
I mostly wanted to share my success at using the stock fuel line pathways, using AN -8 hose. It was tricky, but it worked. The hardest section was running one line over the transmission crossmember mount brackets, and the other line through the lower section of the same mount bracket.

The other small challenge I ran into was (like deja vu) dealing with leaking head studs / MLS head gaskets. The answer here was ginger root tablets, good old BARS LEAKS tabs. Most likely the reason why I could smell burning glycol at WOT in my previous build, it was coolant seeping past the layers of the head gaskets.
The last minor note, I recently saw the winningest Corvette racecar of all time go up for auction at Monterey, hosted by RM auctions. I saw in their photos that the racecars used double hose clamps for the cooling lines. In was one of those no-brainer moments, I realized "I have extra hose clamps, I'm doing that!"
Enjoy,
