Caterpillar 3208 Solutions This sub-forum is hosted by Mike Hohnstein who has been at this kind of thing for 50+ years now, guess I'm addicted. The saga has been all about progressively larger shop space since then. Honestly, never wanted to get into the CAT 3208's that were originally considered to be a throwaway engine but that's all that works in a FC in my world. Same thing with my Ford toter, that came with a NA, too much effort to hang in a 6, so been at it with the CAT V-8 for 20 years now. In reality you can get excellent life out of a CAT 3208 if it's built correctly. Post your questions about the CAT 3208 engines here and Mike will try to help you out.

Default Engine noise at speed?

We here the noise at hwy speed (tack is out right now) Sounds like a high gear noise that last about 3 seconds and a loss of power. It started when I added a aux fuel pump & 40' of 3/8" fuel line (from engine to LPG compartment back to engine. After it started, I installed a fuel pressure gauge before the Ing. pump (reads ave. 4PSI, then when I here the noise it goes to 6PSI). I then added (for testing) a second aux pump at the fuel tank at the bottom of the tank. At first it happens often, now a few times in 5 HRS. what do you think? GOV. or ING pump? Remove the pump in the LPG compartment? Never herd this noise before the pump was added.

Thank you Mike! I am using HD diesel fuel line. What do you think is going on?

I Findley talked to WIX filters and was told I have the wrong filter for my system. Using a booster pump over pressers the filter causing the leak.
What filter should I be using?

What pressure does the 'booster' pump provide?

Looks like a lot of opportunities to suck air. I’d start with installing the proper fitting on the injection pump, then get rid of the rubber fuel hose. Find the copper supply line, runs down the curb side frame rail, tap into that near the propane bay for fuel pump and filter then back to the copper supply line and ditch the fuel hose, barbed fittings and hose clamps. Any hydraulic hose shop can supply proper hose and fittings for everything.

Also, not that it’s part of your current issue, the carter pump you have is a rotary vain pump which I don’t think will allow fuel to flow through in the event the pump fails. The originally installed facet fuel pump is a pulse type. My facet pump wasn’t working but bus ran fine, I have installed a new facet, I think it’s 40109.
