Onan 154-1528 Gasket Kit - Manifold NH. A number of gaskets/kits have been listed as replacements: 154-1482, 154-1483, 154-2747, 154-2748, 154-2219. Presumably, this would replace most or all of those numbers as well, but I don't have them to compare to see if those came with extra pieces.
Item is new, old stock. This means it is brand new but not covered under any factory warranty.
Mechanical items are eligible for a full refund including original shipping if returned within 30 days. Return shipping is the responsibility of the buyer except under certain conditions (e.g. wrong part was sent). Any change in condition of a returned item (e.g. screw marks, fuel residue or other obvious signs of use) will result in a restocking fee at our discretion. Trust me when I say we are reasonable people and I'd rather not have to write any of this, but a few unscrupulous buyers ruin it for the rest of us.
Standard shipping on all small items is USPS Priority. Larger, heavier items will be sent UPS or DHL ground. Items are picked up Monday, Wednesday and Friday by our shipping service, and ship the following business day. I can always expedite shipping at your cost or using your shipping account to save you money--just contact me to make arrangements.
NEED OTHER ONAN/CUMMINS PARTS? This is a part time business for us. What that means is that at any given time we have thousands more part numbers than we have time to get listed. We are slowly working on a formal inventory, but for the foreseeable future there will be many that are simply organized by type or the generator/engine they were used on. We also have many partial and complete units for pulling parts. If you are looking for something, knowing the model and spec of your unit is essential to me finding it as quickly as possible. Please understand that two of our warehouses are more than an hour away and many items require the assistance of my business partner, the owner and expert, to locate and/or remove. While we can sometimes quickly obtain items for an emergency situation, out current arrangement works best when low price is more important than expediency.
