I want to install a 4 way valve for my three fuel tanks and I can only find 1/4 inch valves. All my lines are 3/8 inch, will using this size valve cause me any problems?

Thanks,
Darren

Bombardier does not make 1/4" fuel hose anymore. The smallest fuel hose they make is 5/16." (The 1/4" hose they do offer is for the remote oil tanks on newer engines.) I would not run any 1/4" fuel connections or hose on that engine. You run the risk of it running lean at full throttle. The 3/8" hose you are running will work just fine. Most marine shops have catalogs which offer various size brass valves. You should be able to order a 3/8" one and get it in a few days.

Thanks, EMD. I finally found a 4 way 3/8 valve and have it installed.
