Native Posted January 17, 2021 Share Posted January 17, 2021 So its seems that my 53 Roadmaster Riviera has an issue with vapor locking. It runs fine as long as the car is moving even in the heat of the summer here in South Florida. I'm considering doing a couple of things. 1 swap mechanical fan for electric. 2. Install an electric pump at the tank to be able to flip on in traffic and push past the vapor lock to the diaphragm pump. Looking for thoughts and input. What have you done and what did you use?

NTX5467 Posted January 17, 2021 Share Posted January 17, 2021 I believe that Old-Tank's "Buick Restorer" section might have an installation of an electric booster pump on his '55 Buick? NTX5467 Link to comment Share on other sites More sharing options...
gdmn852 Posted January 17, 2021 Share Posted January 17, 2021 I would setup an electric Pump as a backup with a switch to turn it on when needed, I did this on a Packard and it worked well having vapor lock issues also when first start up after sitting for awhile.Mount it close as possible to the tank , the ones I had work better pushing fuel than pulling, also add a in line filter. Also check the existing fuel lines and flex hose for leakage ,sometime the will suck air . Link to comment Share on other sites More sharing options...
gdmn852 Posted January 17, 2021 Share Posted January 17, 2021 Check the fuel pump also , if the diaphragm is weak it may not be pumping enough fuel also if is is leaking it may dilute the engine oil , found this out on an expensive lesson on a 1940 Chevrolet.

An electric fan that would match or exceed the output of the mechanical fan would pull more amps than your (probably) 30 amp system can do. 1 1 Link to comment Share on other sites More sharing options...

Dennis, go to my profile, find the threads I started. Should be one on the EFI . Then ask questions and I will answer them if I can. If you are planning on driving much, you will like it.

Dennis Hagen Posted January 20, 2021 Share Posted January 20, 2021 Thanks Ben, I called Norm at Affordable and he said he could build me an efi setup for 1000.00. I assume this is the setup you have, I have already converted to 12v and put in a Pertronic ignition. Just don’t like the vapor lock issues and carb choke issues.

Yes, that sounds like the one I have at that price. They have a newer one that the "computer" can mount under the hood and probably will be neater. For another $500 or so. Having said that, the system I have has been bullet proof. I will be glad to help any way I can. Ben Link to comment Share on other sites More sharing options...
