The GTM Supercar Build Log

Fuel Leak Drama and Alignment

Wednesday afternoon the GTM left me a present in the form of a puddle of fuel under the passenger tank. I traced the leak to the fuel sender unit mount and when I tried tightening down the fuel sender bolts more the leak got worse. I had to pull the fuel tank (after draining all the fuel) and remove the fuel sender unit. A quick inspection showed tears around several of the bolt holes in the tank gasket. I made a quick call to the GM dealer and they had a new pair for me Thursday morning (decided to change the other tank’s gasket as well since I had the passenger tank out already). Unfortunately the gaskets they received were not the correct ones. I promptly ordered another set of gaskets for 97-99 tanks in hopes that they would work. Luckily, I was able to get them overnighted again and got them Friday morning. They were the correct ones and I was able to swap the gaskets and get the tanks reinstalled in a half hour or so. Quick cycle of the fuel pump shows everything to be OK. 

With the fuel situation under control we trailored up the GTM and hauled it to the alignment shop. No surprises (good), and the wheels are aligned properly now. 

The GTM ships Sunday morning.
