There is but it's not replaceable. Those old fuel pumps bolt together.

Ususlly when they need replacing its because they've corroded and leak.

Depends on what line. Use the new easy to bend stuff. You get what you pay for, the cheap stuff can start rusting pretty quickly.

Dude you feel the heater hoses under the hood to make sure they're both hot? Default when there are vacuum problems is usually to blow warm air out the defrost. So cold air indicates its either not getting heat inside or probably a blend door isn't working properly.

Little thin line somewhere going through the firewall. Chances are if its a vacuum problem unless the rubber part where it connects to the intake is hard or split or disconnected the lines for the controls under the dash have broken up. There are several posts about that.

Not fully sure how that one works. If it's the same as the Chrysler one it's semi automatic with a sensor an motorized blend door that can fail and cause issues. And the vacuum lines behind the controls can get brittle and break but doesn't seem to be as much of an issue in places like NY. I...

Wow. I've had a couple 88s stripped down to nothing and never saw build sheets in them. But there's no arguing that- your second pic has an 88 5th Avenue VIN on it. Was it an airbag car? Both the ones I had apart were the earlier non airbag ones.

I think the difference is the charts usually use flange to flange for sizes because it's a fixed measurement. Flange to flange of early F/M is 54.340. And perch is 44.46 Flange to flange of later is an inch wider. Early B body 8 3/4 is usally listed at 55" flange to flange and 44" perch...

No, flange to flange DID change an inch. That's been documented before and I saw that first hand putting a 79 axle in my 88. The only way tread to tread could change and nothing else is if offset or width of the wheels changed. And I think they did go from 6" to 7"? I'm guessing the axle width...

No, they were carbed till the end. Which is a bit odd because trucks got it and those two years got some of the biggest changes in the entire run next to the shift from the 70s to 80s styling.

No. Since they never had efi theres no tank you'll need to be creative.

J Body axle should still be the same dimensions as F/M tho..

That looks like different measurement locations. M body is in the 54-55 range which makes it a match for early B body. Later B body and C body is too wide.

The exact parameters changed almost every year but there was a really simple procedure in the service manual to test the computer without any special equipment. If it hit certain readings at certain intervals and conditions it was good, if it didn't hit the range or it was too fast or slow...

I've only had one computer fail and it was an actual lean burn one with the ballast, which also failed at one point. I've never had a spark control or fuel control one cause issues. Part of the problem with those ones, especially the feedback ones, is they rely on a few sensors and they base...
