Is there any area you can isolate and put air pressure to?
I've added ball valves and pressure gauges to things and then pumped them up.
How much pressure can the fuel system stand between the tank and the IP?
I think I might be suspect of your IP or FFM. Possibly fuel pressure gauge sending...
Been there. The water can't be lower than 25' or it won't suck.
I wish I hadn't plugged my old well. At one time, I was dug down deep enough, I could have put a pit in.
I'm guessing they lied to you.
I seriously doubt autozone would sell tested and balanced injectors
You need to take them to a good rebuilder or contact rockabilly here
Are they Bosch?
If they're just box store crap. Return them and get yours rebuilt and balanced.
Or order Bosch injectors and get them.tested and balanced
I would have gone with the schedule 80, 8, 10 or 12" - or corrugated in similar sizes.
Slotted covered corrugated if that would have been appropriate.
Sometimes you can't go too big.
Sounds like the pipe is the issue
Is it schedule 40 PVC pipe?
Is the 4" schedule 40, the black stuff in the picture?
If it's the black stuff, get the appropriate rubber coupling. You may stub a short piece of 4" pvc out of the Y to use a rubber coupling.
I have used rubber bushings before...
Something isn't right.
Are the Ys the same size on.both ends?
I've glued a fair amount of pvc and never encountered that issue.
Is the Y schedule 40?
Can you see lettering on the Y?
I have a bunch of Y's and T Y's in the basement they're all schedule 40.
What is the diameter of a 4 inch...
I torque everything.
I used to break 3/8 bolts without even noticing they got tight.
Then I got so weak that I couldn't tell anything.
I've been hosed by other people I had do work for me, that didn't use a torque wrench
Both, over and under torqued.
So the Y with the 4" pvc pipe in.it is a different ID on each end?
If so, it must be some type of adapter Y.
Often to go from different types of pipe to PVC, they make rubber couplings with hose clamps.
I'm not really sure what you're asking...
