Classic Mini Fuel Pump Mechanical Hif38 1992-1994
1990 on models of the Mini with 1275cc engines and HIF44 carbs use a different mechanical fuel pump. Driven off the camshaft at the rear of the motor these pumps are generally reliable but when a diaphragm goes bad it can be very serious as often raw gas is pumped into the engine. This dilutes the oil and causes severe wear.
For pre 1990 cars use AZX1818.
For 92 - 94 cars with HIF38 and 5/16" inlet use WND10005.

Question:
So rebuilt my full 1275 with many upgrades from boring cylinders +20 to fully porting the head. I fitted a electric fuel pump as I thought this would be better but I’m having so much h issues trying to get it running. With choke fully out it starts abd runs but as soon as it gets hot it seems to sputter abd then just die. I checked the fuel filter abd there was like a jelly in there so I’m thinking it might be dirty fuel tank as it sat fir 10 years empty as I was rebuilding my car. Also I change the spring in carb to a yellow and got a AAK needle as I thought it might be because of all my upgrades it might not be getting fuel. Wen it dies I try to start it by lifting up the cylinder in the carb to give it more air and it nearly starts. Then when the pump is priming there is literally fuel pouring out the back where the air filter goes. It will run as idle with choke fully out but can’t drive it as wen I do it just dies or pops and squirts then dies. Couple of thoughts. Debating getting a new ignition coil and also putting a manual pump on to see if this will wirk then tuning the carb. Any ideas ?
Answer:
Good question. Hope this helps.
Fuel pump is not likely to be an issue. Not sure which carb you are using but I would suggest the first thing to do if the car was sitting for 10 years is the totally flush the gas tank, fuel lines (back to front) AND rebuild the carb. for sure it sounds like the float is stuck!

Question:
My 1976 mini Clubman has a mechanical fuel pump and when in a climb the engine cuts out. The engine temperature gauge shows normal and the engine is not overheating. After about a half an hour it starts normally and I can continue to drive. In the fault finding process I have replaced the coil and the ignition system which is now electronic but it still cuts out.
Answer:
Hi,
Sounds like it could be a fuel issue, either the fuel pump is not suppling enough fuel at high demand, or the problem may be in the carburetor.
You might try do some tests, fuel pump pressure and volume, they like to run at apx. 2.5 to 3.5 lbs. Volume test, just get a coffee can, disconnect the fuel line, and see how much it is pumping.
If it checks out ok, it could be the carb either vapor locking or clogged, not allowing enough fuel at high demand.
If you have any questions, you can give me a call, I do all of the SU carb rebuilds.
thanks,
Ed
