Fuel pressure regulators will often bleed fuel, but they are easy to check. You just pull the vacuum line off and if there is fuel inside the vacuum line or dripping out the regulator, it is bad.

You could also have a fuel injector dripping, or the fuel pump could be allowing pressure to bleed back into the tank. All very common.

If you have a way, you can hook a fuel pressure gauge on the rail, then install a shut off valve between rail and pump. Turn the key on until you have built fuel pressure, then shut the valve off. Come back the next morning and see if your rail still has pressure. If it does, you know its the fuel pump. If it doesn't, then it's an injector, or the regulator (just leave the vacuum hose off and see if there is a puddle near it).

Thanks Trey!

Definitely will try this, doesn't seem too hard. That was one of teh annoying little problems that wasn't a huge deal but bugged me alot. Appreciate the tip.

Continuing on with disassembling my engine bay. When I started this project, I wasn't sure how far I wanted to go with removing things from the engine bay but after giving it some thought I've decided to take it all out and paint the engine bay. Do a job once and do it right, right?

Not a lot of great pictures to show on this update as I am disconnecting the wiring harness and taking my time to label everything. My plan is to lay it all out on the garage floor and fix any connections that need repair and replace all of the loom.


I'm finding a lot of relays attached the fenders and core support with these plastic clips... doesn't seem too stable!


Also took out the fuel vapor canister. About half the hoses were disconnected which would explain the fuel smell I was getting when driving the car. Debating on putting this back in or not... I'll have to do a bit of research on what it takes to get it working properly or how hard it is to delete.

I kept my fuel canister, even replaced the charcoal element in it. While I deleted most of my emissions equip, the canister is necessary to vent the fuel tank. I just ran one port to the fuel tank vent line and the other port to small vacuum port on the carb.

What Lance said. There may be alternatives to using the canister but you want something to vent the tank and keep the smell away.

Good luck cleaning up the engine bay. You can always check out DSE's 3rd gen for inspiration on what a clean bay looks like on these cars.

Ok I will look into rebuilding the unit and getting a new charcoal element. DSE's car is definitely an inspiration for my build! I love the purposeful and non-flashy look of their car... I hope I can half way there with mine.

I was able to make a ton of progress this weekend on the car. I was able to get the entire steering system out of the engine bay and then dropped the K-member. Here are a few pics:

Steering components out of the car:


I'm still working on getting the Pitman off of the steering box. My puller wasn't working even when I hit it with the impact gun so I'll have to check out some alternate methods. I will be sending the box out to be rebuilt as it has quite a bit of slop in it.

The rest of the steering linkage is definitely going to get replaced... it was looking pretty nasty. I don't think that tie rod has been adjusted in the last 30 years!



I then moved on to the K-member. First I popped the lower ball joints... I was able to get them loose with a few good whacks with the hammer. Again, found a ton of crud and dirt built up on the lower control arms. I think the front end might lose 20lbs in dirt alone!



Next, I put 2 jack stands under the K-member and took out the 6 bolts holding it up. In order to get it out from under the car though, I ended up using a chain to hook it up to my engine crane and lifted it just a bit to get it off of the jack stands so I could remove them.


Then, I lowered it down to the floor, removed the chains and dragged it out the side of the car.


Here it is outside the car with the springs and the sway bar:


I'm torn on how to proceed with the K-member. I'm on a budget, so my original plan was to clean it up and paint it. I was going to add some new bushings and ball joints to the control arms and re-use those as well. However, those tubular K-members and control arms sure are sweet! I'll have to do a bit of research here.

Next up is getting the brake booster out and keep labeling and removing the wiring harness. Little by little!
