Reviews Of Kpm 1000Hp Intank

[Ralph Wiggum]

My one and only concern with intank pumps is how much fuel can you possible push through the stock 5/16 line?

[IH8TOADS]

I'm doing a fair bit of fuel system work this weekend so will have comments after.

[Kosij]

I have a pw surge tank with twin 044's on a 30 degree day after a little driving my fuel temp climbs to 55 degrees. I'm no experienced tuner or mechanic so wouldn't no if that's good or bad. How much does fuel temp really affect it?

[IH8TOADS]

The density of fuel changes with temperature which then affects the injector mass flow rate. It's pretty easy to calculate the resulting difference in AFR using the coefficient of thermal expansion and some simple maths, but I'm on the bus because my fuel system has $hit itself again and I can't be bothered lol. In short you want the most consistent fuel temperature possible.

[Never had any say Panda]

What if you used something similar to a trans oil cooler and instead put it on the return feed to the surge tank..

We have had ours, coupled with a bunch of fault finding and removing pumps for "exchange" then reimbursement, I also believe others across Australia had "issues"

What we very rarely see is "issues" with the trusty 044 on nearly any kind of fuel, for massive durations over years and years, I even have pushed a single 044 to what most would say is stupid power for a huge amount of kms

I know things have "trial" periods and "testing" phases but when a product gets advertised as a e85 pump with claims of said supportive power and ZERO about "time limits" its a bit much especially at the dollar figure said item is/was

Again bosch may put a hr limit on their pumps but the time has already been done on the trusty 044 and as the most popular aftermarket electric fuel pump world wide it certainly has proven to be the goods... If u want any more of my personal opinion on this item I have bulk videos,pictures,data and facts but I wont sledge this product but provide my experience based on e85 use from the time of use/purchase

Jet I believe that you refer to our #1 test intank ute fuel system that was fitted to a common customer of ours.

This system was fitted with the total customer understanding that it was in field testing and the customer needed to return regularly for progressive reports and evaluation on performance and suiatbilty.

The system was fitted out at a hugely reduced price to compensate for the testing requirements during a 6 month period.

What was also specified was that we did not recommend continual E85 usage as we had concerns over pump and system life on extended usage.

What eventuated was a customer that utilised our system at a reduced rate without returning regularly as requested for evaluation.

We made several attempts to have the vehicle return for evaluation as agreed , however this was ignored.

Rather the customer utilised various differing workhops causing him to become confused and dissiluusined by conflicting recommendations on what should have been testing only by the manufacturer workhop..

What eventauted was a vehicle that had returned to us with a fuel system that had been removed, and refitted incorrectly with the return line incorrectly feeding the carbon canister and spilling petrol into the chassis rail. The wiring had been cut and poorly insulated with cumbersome household electrical connectors. The fuel tank had been refitted with hold down strapping and bolts not tensioned.

In short, what should have been a field tested evaluation vehicle , never eventauted.

The disallusioned customer aksed us for the vehicle to be returned back to standard in all aspects, due to all the above.

The result was that 1 fuel pump after 8 months running only E85 wore the brushes and commutator and failed.

The result from agreed montoring would have been an assesmant and conclusion:

System limited to continual E85 usage due to commutator / brush premature wear and eventual failure.

Pump/s would have been replaced before failure and the customer would have been advised not to run E85 only.

Customer would have remained with a perfectly reliable and operational fuel system with a full understanding of any limitations.

This recommendation is now used on every Fuel system we sell.

What we learnt from this experaince was that field testing should only ever be limited to workshop vehicles. This however is sometimes impossible.

This is why manufacturing workshops/companies utilise consenting customers to assist.

In regards to the Bosch 044, KPM are a Bosch Motorsport Australia supplier.

We are in communications with the engineers at Bosch in regards to recommendations and solutions.

The Bosch 044 is in the catagory of limited usage.

We have initiated Bosch Motorsport Australia to source of 100% E85 only suitable pump for our systems.

Until such time , the Streetfighter 1000hP Twin Intank Fuel systems

are

Petrol 100% suitable without restriction

Flex Fuel Usage suitable without restriction

E85 Only usable with time restriction.

FYI, I've been using e85 in the XR6T as long as anyone I know in Perth and I didn't have issues when using Sucrogen on and off. However since running United e85 exclusively since it came to the Osborne Park pump, I've recently run into issues. Basically lambda increases rapidly with positive manifold pressure. I can't confirm what the problem is unfortunately, however I will find out on Sat when I strip the system down, test and replace part by part.

No power to pump. Checked relay and it's a 16 amp and a 20 amp fuse lol. Epic fail.

Ok so im looking to get up into that 600hp / 130mph territory on e85 and your telling me I would need to budget for pump changes every nine months or so if chose to run e85 full time (car is a daily). Alternatively if I run e85 for drags and track days I still need to allow for pump changes at some point. Hmmm. I liked the idea of no external tank but don't know about semi regular pump changes.

[IH8TOADS]

Many people have run non e85 approved pumps for donkey's years whilst others have had dramas here and there. There is a heap of e85 approved pumps around these days....but realistically I think KPM are just covering heir ar$e and being very cautious.
