Does Cat fuel priming pump fit on a Winnebago Journey?

I'm getting ready to change fuel filters for the first time on my 2007 Journey, C7 Cat. It is the 34 foot model. After reading about all the issues with pre-fill, don't pre-fill, etc., I think adding the primer is the way to go. The dealer in town has it in stock.

The engine access is under the bed, but I haven't pulled it off yet to see what I am dealing with. I'm not even sure that would tell me much as I don't know how big the Cat pump is.

Can anybody tell me if there is enough clearance between the engine cover and the fuel filter mounting flange to add the pump?

Thanks much!

    A Facet or Holley red pump will do the job much easier. Have 10 years running electric pusher pumps with check valve on inlet side, controlled by oil pressure switch and momentary push button to facilitate filter changes, 3208 Cat engine. Cat manual pumps are known for air leakage.

    Yup, there are other options, but the manual pump is the solution that makes changing filters and priming very easy. Most chassis/coaches came with them.

    Suspect some bean counter at the chassis maker saw a way to save a couple of bucks.

    I'm sure Cat will let you bring it back if it will not fit although I THINK it will. Since you are in CO I'd park it on a steep hill with a full fuel tank... nose up. I'd prefill the filter and just change it quickly. If you needed to change it in SE Fla it would be hard to find a hill that gets the fuel in the tank as high as the filter. Another option is to put a valve in the fuel line at the engine so the fuel cannot suck air into the line. You still have to prefill the filter with clean fuel.

    There are adapters so that the Caterpillar manual primer pump can be installed at 45 or 90 degrees to the mounting plate. See what works best for you OR even better move the secondary filter to a more accessible location (as many manufacturers did when they built the coach).

    The secondary filter (the one with the manual pump) needs to stay in the same position in terms of fuel flow (between lift pump and engine) but can physically be mounted anywhere.
