    510 Door Seal

    You nailed it. I ordered the Precision first, and when they didn’t fit well, I told myself to pony up the extra dough and get the Vintage Rubber seals. I might order a set of Datsport seals. I see people have goods things to say about their products. I wish they had a typical online ordering system.

    510 Door Seal

    I would like to keep the factory look but these aftermarket seals are testing my patience. I think I’ll try the bulb seal you guys suggested. I appreciate the info.
  3. Anyone have experience installing either Precision or Vintage Rubber Door seals on a 510? After installing the seal the door doesn’t want to close. If feels like the seal is interfering with the body side. To determine the location of the interference, I cut a 12inch piece and mounted it in different locations around the door. It appears the problem is coming from the front of the door. I’ve tried both brands. The shape of both are very similar. The Vintage is a slightly better but still interfering. Any install tips or suggestions for another seal would be appreciated.
  4. Hey Ted, I’m currently using one from McMaster. It’s a little light but it works ok and fits right in.. https://www.mcmaster.com/9657K702/
  5. Crash: I haven't noticed it at low RPM's under hard acceleration. I'll check later to confirm. I would say it happens around 2500-3500K RPM and continues until I lift.
  6. Mike: I had previously checked around the exhaust for any signs of rubbing and I couldn't find any, specifically around the rear cross-member. The entire exhaust system is firmly mounted. It doesn't move at all when you push on it. Not sure if that's a good thing. I'll check the exhaust system again to confirm.
  7. The rattling sound starts at 1, 3 and 6 seconds into the video. I've been all over the car checking to make sure nothing is loose. I only hear the sound under hard acceleration. Specs are below. 72 510 L18 5spd Z trans 32/36 Weber
  8. I need some help identifying a sound. It's a high pitch rattling that happens under hard acceleration. I uploaded a quick video to YouTube. The link is below.
  9. It’s been several months but I finally found time to work on my 510 and run some tests. I wanted to share my results. 1. I disconnected the fuel line after the pump. Turned on the pump and the flow wasn’t that great. I removed the gas cap. No change. 2. I removed the pump and put the inlet hose in a full gas can, the outlet hose in an empty gas can and turned on the pump. The flow was excellent. Based on these tests, it appears I have some type of restriction in the tank. I removed the tank and had it cleaned and sealed by a local shop. I installed the cleaned and sealed tank using a new hose and the electric fuel pump I previously tested. Assuming the tank was the only problem, I connected everything up to the engine compartment. My plan was to turn on the pump and purge any junk that might be in the hard line before connecting to the carb. I did this and the flow was almost zero. It was a minute or so before any gas would come out. I went back and disconnected the fuel hose after the pump and tested the pump again. The flow was strong. It appears the hard fuel line has some type of restriction or build up as well. I visually inspected the hard line. I didn’t see any damage so there must be some blockage. At this point, I decided to replace the hard line. I ordered a roll of 5/16 aluminum tube. I removed the original hard fuel line and used it as a guide to bend the new aluminum line. I started in the middle and worked my way out. I used zip ties to hold the two lines together. I used a 90 degree tube bender and spring to bend the aluminum line. I used a beading tool to flare the ends for rubber hose and a deburring tool and scotch-brite pad to clean the ends. I replaced the stock fuel line mounts with 5/16 stainless mounts. I used the same mounting holes. The entire process went quick. Less than a day from start to finish. I connected everything again up to the engine compartment. I wanted to run the pump and purge any aluminum debris left over from cutting the line. I had strong flow as soon as I turned on the pump. I finished the connection to the carb. I cranked the engine and it started immediately. Nice. Time to tune the carb. I appreciate all the advice. The image below shows the current location of the electric fuel pump. This is under the car in front of the right rear suspension arm. Nice gravity feed from the tank.
  10. I appreciate the ideas. This is what I’m thinking. I’m going to disconnect the out line from the pump and see if anything changes. I will also try to remove the gas cap. By doing this it should eliminate the fuel line under the car. If no change, I will test the pump using a gas can. If the pump works, it must be a problem with the tank. The car ran before, but not very well. There could be some problem with the tank. Im using the lower outlet (smaller diameter) in the tank. I think the return line is the top one (larger diameter), correct?
  11. I replaced my Weber 32/36 carb on my 72 510 with a new one. The mechanical fuel pump was also shot, so I decided to replace it with an electric fuel pump. I’m having trouble with the electric fuel pump. It doesn’t have enough “push” to get fuel to the carb. Electric Fuel Pump Setup: I used an Airtex 2.5-4psi rotary type in-line fuel pump. Mounted just underneath the front of the fuel tank, behind the rear seat. I used the extra switched circuit in the fuse box for the hot side. I ran the ground side through an inertia switch mounted under the dash. I used a Russell 40 Micron fuel filter between the tank and pump. I used a clear stock type paper fuel filter between the pump and carb. I use ¼ rubber hose for inside fuel lines. I used the stock hard fuel line under the car. Result: When I turn the ignition, the fuel pump starts as it should, but very little fuel makes it to the clear paper filter and it took several minutes to get there. It filled the filter to just below the element. In addition, the pump got hot. I tried each one of the ideas below, one at a time, with no improvement. 1. Removed the paper filter. 2. Bypassed the fuse box and ignition switch. Ran hot right to the battery. 3. Removed the Russel 40 micron filter. 4. Installed an AC Delco 2.5 - 4psi in-line electric fuel pump. Same as installed on “Zeke”. Other things I checked. 1. Disconnected the fuel line at the carb. Ran the pump. Very little fuel, took several minutes to get there. 2. Check the float chamber. Very little fuel. 3. Confirmed 12v at the pump. Any thoughts would be appreciated.
  12. I wanted to give an update on my issue. This is what I did. 1. Checked all the grounds for the lights. No problem here. 2. Cleaned the white wire connector coming out of the fuse box. This looked good before cleaning but wanted to be sure. 3. Cleaned and soaked the fuse box in lemon juice and salt. This worked amazing. Also used a brush with a dremel on low speed to do a final cleaning. The result was good. The park/tail fuse was much cooler. Still a fuzz warm. No where near what it was. Then I discovered a mistake on my part. When I replaced the park/brake bulb receptacles, I switched the park and brake wires. So when I would turn on the parking lights, the brighter 1/2 of the bulb would light up, using more power. I switched this and the fuse box is nice and cool.. i appreciate all the suggestions and advice.
  13. I’ll do that as well. Thanks Banzai.
  14. I’ll check the grounds and try cleaning the fuse box. I’ve used this same mixture to clean my hands after handling mahogany wood. Worked awesome. Thanks guys.
  15. Hey guys, I need some help with my 72 510. The park/tail fuse terminal gets hot when I turn on the parking lights. Only the outside terminal. This is what I’ve tried so far. Replaced the fuse Cleaned the fuse box terminals Swapped out the fuse box Swapped out the light switch Unplugged all the rear lights (This seemed to help. The terminal stayed somewhat cool. Maybe a fuzz hotter.) The wiring on this car was a mess when I bought it. I’ve been slowly cleaning it up. Any suggestions would be appreciated.
