Throttle body modification...

[Master Guns]

Just going to leave this here for your viewing pleasure. 

 

Picked up this great condition project on Marketplace late June...been working on it intermittently, with help from many discussions on this forum (you guys are great).  I'm the 4th owner now.  

 

From the day I picked her up, there had been the faint smell of fuel in the engine bay and interior of the cab.  Truck had been sitting in the third owner's driveway for around four years, they'd only added about 100 miles since they'd bought it in 2021.  Replaced the battery and drove her around 65 miles one way to my place, with zero issues, albeit the faint fuel smell.  Never a puddle or any indication of a leak.  Previous owner did indicate they'd replaced the gas tank and lines.  Clearly all new parts, correctly installed, upon deeper inspection.  

 

After a few weeks of other more pressing repairs and upgrades, I decided to really track down this smell.  Started with the vapor canister filter and new vacuum lines.  Those were fairly easy fixes, but didn't solve the smell.  Picked up a brand new gas cap too...thought maybe?  

 

Finally, after driving her more and more, the smell was getting worse, and one afternoon while idling and searching and searching, I FINALLY saw the leak dripping slowly from the rear of the throttle body...check out these pictures!  Someone along the way JB WELDED a crack in the throttle body!!!! 

 

Had a hell of a time finding a replacement for the 2.5...but found one in great shape on eBay for under $200, swapped them out and smell is gone now.  

 

My children were in this truck y'all....

Good catch!

 

Looks like a nice truck.

Wow….never seen such lack of care for removing the fuel lines from a TBI. That could’ve been scary.
