Diesel Fuel System Repair Jerome, Idaho
Diesel fuel system repair in Jerome, Idaho covers everything between the tank and the injectors. Hard starts, low power, air in the fuel, or a truck that gelled up in a cold snap — The Semi Shop fixes it in the bay or roadside on I-84. Call (208) 696-9888.
What does fuel system repair include?
We work the whole fuel path: tank pickups and crossover lines, lift pumps, fuel filters and water separators, high-pressure pumps, fuel lines, and the return side. On Cummins, Detroit, PACCAR, and CAT engines we check fuel pressure and look for air in the fuel — a tiny suction-side leak can cause hard starts and stumbles that drive people crazy for months.
We also test fuel quality. Water, algae growth in the tank, or a load of bad fuel can plug filters fast and damage pumps and injectors downstream. If the fuel is the problem, we tell you before it wrecks expensive parts.
Gelled fuel rescue in Idaho winters
Cold snap hits and the truck dies at idle or won't start at all — that's gelled diesel, and it happens every winter on this stretch of I-84. We come to you, get the fuel flowing with the right treatment and fresh filters, and get you rolling. We run gelled fuel rescue to any I-84 exit from Bliss to Declo, 7 AM to 10 PM every day, flat call-out fee stated before we roll.
How long does fuel system repair take?
Filters and a gel rescue are usually handled within hours. Lift pumps and line repairs are often same-day. A high-pressure pump job takes longer, and we quote the time along with the price. Diagnosis comes first, so we're fixing the actual fault, not throwing parts at it.
What to expect: quote first, price is the price
After diagnosis you get a firm quote, and the price we quote is the price you pay. Harvest season doesn't wait on a truck that cranks but won't fire — and neither should you. We're minutes off I-84 exit 168 in Jerome, and a local answers the phone.
Driver questions
My truck cranks but won't start. Is it the fuel system?
Often, yes — air in the fuel, a dead lift pump, plugged filters, or gelled fuel in winter are the usual suspects. Call (208) 696-9888, tell us what it's doing, and we can come to you at any I-84 exit from Bliss to Declo.
At what temperature does diesel fuel gel?
Untreated #2 diesel can start clouding in the teens and gel as it gets colder — right in the range of a normal Magic Valley cold snap. Winter blend and anti-gel additive prevent most of it. If it's already gelled, we can rescue it roadside.
How often should fuel filters be changed on a semi?
Most trucks do well with filters at every service interval, and sooner if you've taken on questionable fuel. If filters are plugging fast between changes, something is wrong in the tank — worth a look before it takes out a pump.
