Transfer Pump Replacement- Electronic for 8.3 350hp ISC

December 26, 2020, 08:36:57 pm

Greetings.

Today I was checking out the condition of my fuel lines. Not too bad. I did confirm that I have a drip from the transfer pump when I turn the ignition to the accessory position. The pump is definitely working but I think it has to be the typical bad gasket issue.

Any advice for someone who has not done this before would be greatly appreciated.

For instance-
1. Is any preparation required prior to removing each fuel line? (4) total, Correct?
2. It seems easiest to do this from above the engine, through the raised bed opening. Correct?
3. Any special tools which I should know about?
4. I have read on the forum that there is not the need to prime the lines after new pump is in place and lines connected. Correct?

I am assuming the entire assembly needs to be replaced, not just the pump motor and gasket.

I may decide to go with a Fass Titanium System. I am researching whether that makes sense on an older coach.

New to RVing. Learning as I go.

Thanks for your time.

If your going to change the pump loosen the fuel lines before you take the pump loose.

Where it me would go the Fass system from Brazils RV service. Not much more than a stock transfer pump.
