Polyester resin air intake

 

What the? Looks like something that came out an Egyptian pyramid. It doesn't even look like air can pass thru it. You went from OEM cold air intake to hot stifle.

 

It's certainly not pretty to look at, but I don't see any functional concerns. What was the goal here, and what is the black hose for?

 

The car is running with GPL ( same gas used for cooking )so it was needed an intake for the new fuel.... I do not think I can find such a part on the market. I run the car for short time and everithing seems ok, but now I am worried that the part can became too hot and melt !!
As I said on another post I am in dominican republic so everithing is a compromise, and fixing this old car is a kind of an hobby for me.

 

GPL, which is also LPG. Nice. How are you regulating fuel intake?

Polyester resin may have been a mistake, If you still have the original throttle body hat, I'd use that. So long as you're sealed from the point you put the fuel in to the throttle body you should be good. If not, try getting some high temp epoxy resin and redo it. What you used can handle 150 to 300 degrees F, or 65 to 149 C, for short periods. High temp epoxy can take upwards to 600 F or 315 C, which is high enough that if the engine hits it it's not going any further anyway.

There's different grades of the PVC piping you used as well, make sure the stuff you used can tolerate heat. There should be writing on it, and from there the internet should be able to tell you exactly what you used and what its heat tolerance is.

Since you already have this made, no need to run right out and replace it. Monitor it over the next few months and see how it does. If it holds up after being run on your hottest days, it should be fine as it is, If nothing else you can call this a proof of concept if the truck runs and drives like this.

 

This is an old system, no electronics....the gas arrives straight from the tank to the gray circular box that you see on the left corner of the picture. The box has a membrane inside. That's it. In my opinion the idle at minimum is a little rough, but I do not have the knoledge to give a judgment....is just my impression. In the future hope to fix the fuel pump and run it also with gas, so I will see if there are any improvements !!

 

Cool. I'd suggest hitting up some RV (Recreational Vehicle) sites for help on this as well. Converting generators from petrol to GPL is something those folks do, and they may be able to offer advice on how to improve your system. Good luck with it.

 

Hey, my apologies for the earlier comment. Thought you were one those "cold air intake" modifiers who end up with a worse system.

 

No apologize needed...and thank you to everybody, I will post about what is going on.... I am wondering if in the forum anybodyelse is running with LPG .....

 

Not generally on forums like this one, because LPG lowers power and performance. It occurs to me that you might try ecomodders.com as they're more of a green site, and LPG is considered greener than gasoline. They also like to build their own, much like you're doing, so you might get better advice on how to make it work right. Not saying nobody here CAN, just that the likelyhood of getting help with an LPG conversion is better there.
