Walbro pump installation questions
I've spent many hours searching and reading about doing this installation, and while it at first seems pretty straight forward, I've developed a number of questions I would appreciate help with.
It seems like I can just put the pump in-line with the supply line and draw from and through the stock pump. Is this correct? I know a draw tube seems the preferred way, but would rather stay as simple as possible at this time. Is the larger fuel line the one going to the CP3? I've gleaned I need a by-pass pressure regulator, where do I send the by-pass to? Can it be spliced into the present return line, do I need a new line with a dedicated entry to the fuel tank? What's the big deal about putting on bigger fuel lines if your just going to turn the pressure down anyway? I know I need to run pump off a relay and need a fuel strainer before the pump Thanks for the help. |

You'll be done with it and down the road if you want to upgrade.... that part is done. There's only 2 nuts holding the tank up and when it's mostly empty, it can be done with just yourself Here's a picture of my old Walbro installed..... http://i237.photobucket.com/albums/f...k/walbro25.jpg Is the larger fuel line the one going to the CP3?

yes, you can do that but, drawing through the stock pump can cause not only a restriction but, cavatation too. You'd also have to go find the fittings to tap into the stock metal line.
Discovered (figured out) that I don't have in tank pump. Have the one on the side of the filter canister IMO, just dropping the tank and putting the draw straw in is as easy as what you want to do.

We're you using a regulator such as described in the "roll yer own" thread? http://i237.photobucket.com/albums/f...k/walbro25.jpg The fuel line you want is metal and it goes from the tank to the fuel filter. From there it goes to the CP3 Both my lines are metal. see above picture. The return goes to the fuel filler tube I'll have to check this out better. Splicing into return line is a no no? The deal is for those who need a lot more fuel than the stock lines are capable of moving you don't need a filter before the pump although it won't hurt much. Just make sure it's a high flow filter. If you purchased a walbro 392 kit, it should have had the relay with it. |
