i'm pretty excited to get it on the road and hear how it sounds, hoping for a month or two of driving around and working out the kinks before the snow hits and i park it for the winter. biggest hurdle now is saving up for a tune which i want to talk to Moe about soon
Keep an eye on that Aeromotive AFPR. Over the past 20+ years of helping LT1 owners on sites like this, I have seen many failures of that specific part. They start leaking internally. Aeromotive initially blamed it on their failure to update the internal materials to reflect the changing composition of pump gas, but that was almost 20 years ago, and they are still failing.
I had no idea that was a common issue but mine leaked bad!Quote:

i hadn't heard about that but will keep an eye on it for sure. hopefully they'd warranty it if it does start to leak, i got it from summit and they are usually pretty good about stuff like that.Quote:

But over the years, way too many times when I've responded to a description of an LT1 poor running problem, and asked what brand the AFPR was, it turns out it is almost always an Aeromotive, and it's leaking.
I know Aeromotive makes some good fuel system components, and it always makes me wonder what is so difficult about the LT1 AFPR that they can't fix the problem. Guess it's the same as MSD - they make killer ignition systems, but their Opti's are plagued with one problem after another.
What is it just a diaphragm and springs right? With check valves and such. Wonder why? Is there an alternative ?

In my limited experience, its been leaky O rings.Quote:

decided to pull the sending unit last night to start figuring out what i want to do for the dual in-tank walbro 255's. was made much easier by the trap door mod i did 6 years ago when i installed the single walbro 255. only regret is how many screws i used, could've used half that amount and i would've been fine lol oh well. anyways, been looking at some old threads on cz28 forum and this one trying to get an idea of what other people have done. thinking i will wire it so one pump will be on all the time (like factory) and have the second pump come on at around 4-5psi of boost using a boost pressure switch. still trying to figure out the wiring and unfortunately all the pics in the threads i am looking at are gone at this point. i am thinking i can get this all done for under $200 since i already have a walbro 255 so just need another one, some submersible fuel line/clamps, y block, pressure switch, relays and wire which i may already have enough of. if anyone has any input or pics of their dual in-tank setup feel free to post them too.
here are some pics from last night

Use a hobbs switch. Inexpensive, effective, and would be easy for you to install.

isn't that essentially the same thing? was planning on snagging one off ebay and when i searched "boost pressure switch" i was getting hobbs switches popping up as well.Quote:
