Hi all - I am re-doing the carpet in my '78 280z which entails sanding some rust, POR15 sealer, dynamat, etc. When I took off the carpet and sound deadener, I found these two holes that look like they're supposed to have body plugs, but don't. Any idea if these are supposed to stay open, or if there are plugs that are supposed to be in here, are they're available at a local parts store? These are in the passenger side footwell to the left of the fuse box. The one on the left is at the beginning of the transmission tunnel and the one on the right is through the firewall. NOTE: I've boxed both holes in blue with arrows pointing to them. The gray shown on the left side is just the lighting - that is a hole.

Ya - I had one of those clear paper filters that everyone has. fuel pump filter

Gotcha - so me knocking it loose in that case sent it to the engine, was caught by the fuel filter in the engine bay, and the car now runs great since that blockage is gone is what it sounds like?

Were they stuck with gelatinated gas or internal rust?

so far its running and ive been doing just that. thoughts on what clogged the fuel pump even though there was an in-line fuel filter between the tank and pump?

The gas in my tank is probably ~6 months old at this point and the car had been sitting for around 2 months (without fuel stabilizer in the tank) while I am redoing its interior. I was traveling a lot for work and when I returned and tried to start the car, the battery was dead. After charging it, I found that the car wasn't starting and traced it to the fuel pump. After a lot of poking and prodding with the test light I found that the wires to and from the pump were getting pretty hot so I gave the pump a few smacks with a hammer, as some orange gas was starting to sneak its way out around the hose (not a great color for gas), and it started right up and I let it idle for ~20 minutes while I added fuel stabilizer. Question - the car ran great, do I need to dump the tank? Should I replace the fuel pump if it's working now (its only about a year old)? did the pump somehow rust shut internally (the tank is around 3/4 full with 93 octane fuel which probably has ethanol in it).

Awesome, thanks! I took a look at my plug, and there's nowhere the notch would catch on. I'm just curious why its even there to begin with at this point haha.

Hi gang, I'm changing the oil and it looks like the crush washer for the oil pan drain plug bolt has a small cutout on one side. Does anyone remember if the side with the small notch cutout go against the back of the plug bolt, or does the side with the cutout touch the oil pan? You can see the cutout on thezstore's page here any ideas? -chase

Case closed update: I had my seats re-foamed and the ride is great now. I was surprised how big a difference that made, but we're sitting pretty now. Thanks all!

Got it, I'll give it a look. Thanks!

Do you mean pull the cowl plate off and look or looking up from the passenger footwell?

Gang - I'm also in a classic British car restoration forum and they had a really cool thread idea that I wanted to bring here: Did you buy your Datsun brand new and you still own it to this day? If so, please post the oldest photo of you & your car in this thread, and maybe write a little story about what prompted you to buy it at the time! * Also welcome in this thread are stories & photos from Z owners where another family member (parent, grandparent, etc) bought the car new and it has stayed in the family until present day Looking forward to reading your story! I know @jfa.series1 has one!

Thanks Jim! This is what I'd used in the past whenever I found some sneaking around: https://www.amazon.com/dp/B00Q0I62IU?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_2. Thoughts on this por15 offering?

I was planning on sealing the rust with por15 which works really well in a similar sense

Why for dynamat specifically?
